Background

However, the electric energy used for crushing the cement materials by the vertical mill is only partial, and the other part of the electric energy is consumed in other aspects and mainly converted into heat energy and sound energy to disappear, which is a great waste. In order to reduce certain electric energy loss and achieve the effect of energy saving under the condition of not influencing the milling efficiency, the part of converting electric energy into sound energy and heat energy can be improved; the energy-saving effect is achieved by designing the vertical grinding disc which reduces the loss of sound energy and heat energy.

Such design guarantees that the clearance between two adjacent first arc sieve boards allows the size of passing through the cement material granule to be less than the size that first sieve mesh allowed to pass through the cement material granule, just so can maintain the cement material granule size of crossing clearance between two adjacent first arc sieve boards and first sieve mesh and reach the design requirement.

As a further improvement of the present technology, the first spring and the second spring are both compression springs; when first spring and second spring all uncompressed, first arc guide block is located the top of first arc guide slot, and second arc guide block is located the top of second arc guide slot, and the one end that arc slider was kept away from to first arc sieve stretches out first sieve slip logical groove and first square sieve mesh is located on the dish face of hanging of annular bushing, and the one end that arc slider was kept away from to second arc sieve stretches out second sieve slip logical groove and second square sieve mesh is located on the dish face of hanging of annular bushing.

As a further improvement of the technology, the distance from the top wall surface of the first square sieve pore to the end surface of the first arc sieve plate far away from the arc slide block is D1, the distance from the top groove surface of the first arc slide groove to the upper disc surface of the annular lining disc is D2, and D1 is equal to D2; such design is guaranteed, after first arc sieve is extrudeed downwards, when the one end terminal surface that arc slider was kept away from to first arc sieve reached coplane state with the quotation on the annular bushing dish, first bracer inserted in corresponding first party sieve mesh, first bracer can laminate mutually with the roof face of corresponding first party sieve mesh, first bracer just can play the supporting role to first arc sieve like this, avoids first party sieve mesh to produce after receiving too big holding down force and warp. The distance between the top wall surface of the second square sieve pore and the end surface of one end, far away from the arc-shaped slide block, of the second arc-shaped sieve plate is D3, the distance between the top groove surface of the second arc-shaped slide groove and the disc surface on the annular lining disc is D4, and D3 is equal to D4. Such design guarantees, after second arc sieve is extrudeed downwards, when the second arc sieve kept away from the one end terminal surface of arc slider and annular bushing upper disc quotation and reached coplane state, the second supporting shoe inserts in corresponding second side square sieve mesh, the second supporting shoe can laminate mutually with the roof face of corresponding second side square sieve mesh, the second supporting shoe just can play the supporting role to second arc sieve like this, avoid second side square sieve mesh to produce after receiving too big holding down force and warp.

As a further improvement of the technology, when the first supporting block on the first arc-shaped supporting plate is in contact with the inner arc surface of the first arc-shaped sieve plate which is not provided with the first square sieve pore, the first plate spring is in a compressed state; when the second supporting block on the second arc supporting plate is in contact with the outer arc surface of the second arc sieve plate, which is not provided with the second square sieve hole, the second plate spring is in a compressed state.

The lining disc and the lining sleeve have the effects that after the lining sleeve is contacted with the lining disc, under the pressure of the pressure mechanism, relatively large pressure exists between the lining sleeves, and after cement material particles enter the lining sleeve and the lining disc, the lining sleeve and the lining disc are mutually extruded and matched to grind the cement material particles into powder reaching the standard. In addition, the lining disc and the lining sleeve are relatively worn and can be replaced after being used for a period of time.

For the bush in the grinding roller combination, at the bush and the mutual extrusion crocus in-process of lining dish, the mill body is driving the lining dish rotatory, so at extrusion crocus in-process, the lining dish can drive the bush rotatory around the axis of rotary column, and the bush drives conical grinding roller and rotary column rotation.

The bush matched with flow in first arc sieve and second arc sieve and the grinding roller combination: firstly, when a bushing in the grinding roller combination does not move downwards and is mutually extruded with a bushing disc for grinding powder, the first arc-shaped sieve plate and the second arc-shaped sieve plate are not pressed downwards; at the moment, the first spring and the second spring are not compressed, the first arc-shaped guide block is located at the top end of the first arc-shaped guide groove, the second arc-shaped guide block is located at the top end of the second arc-shaped guide groove, one end, far away from the arc-shaped sliding block, of the first arc-shaped sieve plate stretches out the first sieve plate sliding through groove, the first square sieve hole is located on the upper disc surface of the annular lining disc, and one end, far away from the arc-shaped sliding block, of the second arc-shaped sieve plate stretches out the second sieve plate sliding through groove, and the second square. Second, when the bush in the grinding roller combination and the in-process of the mutual extrusion crocus of lining dish, because the grinding roller body drives first arc sieve and second arc sieve rotation, the fillet of first arc sieve and second arc sieve will be extruded to the bush so, first arc sieve and second arc sieve are extruded the downstream, first arc sieve and second arc sieve make the arc slider downstream, first arc guide block and second arc guide block follow the arc slider motion, first spring and second spring are compressed. Thirdly, when the first arc-shaped sieve plate is extruded downwards, the end face of one end of the first arc-shaped sieve plate, which is far away from the arc-shaped sliding block, and the upper disc surface of the annular lining disc are in a coplanar state; after the second arc-shaped sieve plate is extruded downwards, when the end face of one end, far away from the arc-shaped slide block, of the second arc-shaped sieve plate and the upper disc surface of the annular lining disc are in a coplanar state, the arc-shaped slide block moves downwards to a position where the end face of the second arc-shaped sieve plate is in contact with the bottom groove surface of the arc-shaped slide block sliding groove, and the arc-shaped slide block cannot move downwards continuously at the moment. Fourthly, after the first arc-shaped sieve plate and the second arc-shaped sieve plate are not extruded by the bushings any more, under the reset action of the first spring and the second spring, the first arc-shaped guide block and the second arc-shaped guide block enable the arc-shaped sliding block to move and reset to the original position, and the first arc-shaped sieve plate and the second arc-shaped sieve plate move upwards to the original position.

The size of first side sieve mesh is greater than the design of the size of second side sieve mesh and lies in: the cement material particles fall to the middle position of the grinding disc body, then the rotary grinding disc body drives the cement material particles to rotate, and the cement material particles move to the periphery of the grinding disc body under the action of centrifugal force. At the in-process of cement material granule to the peripheral motion of mill disk body, big cement material granule fails to pass through first square sieve mesh, and medium cement material granule and little cement material granule pass through first square sieve mesh, but medium cement material granule fails to pass through second square sieve mesh, and little cement material granule can pass through second square sieve mesh. In a word, under the screening of first arc sieve board and second arc sieve board, big cement material granule is detained between first arc sieve board and the interior disc of ring mill groove, and medium cement material granule is detained between first arc sieve board and second arc sieve board, and little cement material granule is detained between second arc sieve board and the outer disc of ring mill groove.

One end of each of the two support columns is fixedly arranged on the top groove surface of the arc-shaped sliding block sliding groove, and the other end of each of the two support columns respectively penetrates through two column holes in the arc-shaped sliding block and is fixedly arranged on the bottom groove surface of the arc-shaped sliding block sliding groove; the design is that the arc-shaped sliding block can slide on the supporting column; in addition, the support column can well play a good supporting role in the grinding disc body on the upper part of the arc-shaped sliding block sliding groove, and the grinding disc body on the upper part of the arc-shaped sliding block sliding groove is prevented from deforming under heavy pressure.

The first support block on the first arc-shaped support plate and the inclined plane on the first support block are matched with the first square sieve pore on the first arc-shaped sieve plate; the second supporting shoe on the second arc backup pad and the inclined plane on the second supporting shoe and the second square sieve mesh matched with flow on the second arc sieve are: firstly, when the first arc-shaped sieve plate and the second arc-shaped sieve plate are not pressed down, a first supporting block on the first arc-shaped supporting plate is in contact with an inner arc surface of the first arc-shaped sieve plate, which is not provided with a first square sieve hole, and a first plate spring is in a compressed state; the second supporting block on the second arc-shaped supporting plate is in contact with the outer arc surface of the second arc-shaped sieve plate, which is not provided with the second square sieve mesh, and the second plate spring is in a compressed state. Secondly, in the process that the first arc-shaped sieve plate and the second arc-shaped sieve plate are pressed downwards, when the first supporting block is opposite to the corresponding first square sieve hole on the first arc-shaped sieve plate, under the reset action of the first plate spring, the first supporting block on the first arc-shaped supporting plate is quickly inserted into the corresponding first square sieve hole; when the second supporting block is opposite to the corresponding second square sieve pore position on the second arc-shaped sieve plate, the second supporting block on the second arc-shaped supporting plate is quickly inserted into the corresponding second square sieve pore under the reset action of the second plate spring. Thirdly, in the process that the first arc-shaped sieve plate and the second arc-shaped sieve plate move upwards and reset, the bottom wall surface of the first square sieve hole on the first arc-shaped sieve plate can extrude the inclined surface of the first supporting block, so that the first supporting block drives the first arc-shaped supporting plate to move towards the first plate spring under the extrusion force of the first supporting block, and the first plate spring is compressed until the first supporting block is completely extruded to be separated from the first square sieve hole; the inclined plane of second supporting shoe can be extruded to the diapire face of the second square sieve mesh on the second arc sieve board, so the second supporting shoe under the extrusion force, the second supporting shoe drives second arc backup pad and removes to second leaf spring direction, and the second leaf spring is compressed, breaks away from out the second square sieve mesh until the second supporting shoe is extruded completely.

The first arc-shaped sliding groove can completely meet the condition that the first supporting block in the first arc-shaped supporting plate extends out of the first arc-shaped sliding groove. The second arc-shaped sliding groove can completely meet the condition that the second supporting block in the second arc-shaped supporting plate extends out of the second arc-shaped sliding groove.

For the first expansion plate: first expansion plate is flexible at the removal in-process of first arc backup pad, and first expansion plate has played the confined effect to the removal orbit of first arc backup pad, prevents rocking of first arc backup pad to cause first supporting block to be difficult to get into corresponding first party sieve mesh. For the second expansion plate: the second expansion plate stretches out and draws back at the removal in-process of second arc backup pad, and the second expansion plate has played the limited action to the removal orbit of second arc backup pad, prevents rocking of second arc backup pad to cause the second supporting shoe to be difficult to get into in the corresponding second square sieve mesh.

When the vertical grinding disc does not work, the grinding roller combination is positioned on the upper side of the grinding disc body, and a lining in the grinding roller combination is not in contact with the first arc-shaped sieve plate and the second arc-shaped sieve plate; first spring and second spring all uncompressed, first arc guide block is located the top of first arc guide slot, second arc guide block is located the top of second arc guide slot, the one end that first arc sieve kept away from the arc slider stretches out first sieve slip logical groove and first square sieve mesh and is located on the dish face is coiled to annular bushing, the one end that the arc slider was kept away from to second arc sieve stretches out second sieve slip logical groove and second square sieve mesh and is located on the dish face is coiled to annular bushing. The first support block on the first arc-shaped support plate is in contact with the inner arc surface of the first arc-shaped sieve plate, which is not provided with the first square sieve pore, and the first plate spring is in a compressed state; the second supporting block on the second arc-shaped supporting plate is in contact with the outer arc surface of the second arc-shaped sieve plate, which is not provided with the second square sieve mesh, and the second plate spring is in a compressed state.

In the working process of the conical grinding roller, the diameter of the outer conical surface of the conical grinding roller close to the middle of the grinding disc body is smaller than that of the outer conical surface of the conical grinding roller close to the outer circular surface of the grinding disc body, the conical end of the conical grinding roller close to the middle of the grinding disc body is a front conical end, and the conical end of the conical grinding roller close to the outer circular surface of the grinding disc body is a rear conical end. That is, the diameter of the outer conical surface of the front cone end of the conical grinding roller is smaller than the diameter of the outer conical surface of the rear cone end of the conical grinding roller.

When the vertical grinding disc of the invention grinds cement materials, the driving mechanism acts and drives the grinding disc body and the annular lining disc to rotate through the supporting turntable; then, the material conveying mechanism on the upper side of the grinding disc body drops the cement materials at the middle position of the grinding disc body, the rotating grinding disc body drives the cement material particles to rotate, and the cement material particles move to the periphery of the grinding disc body under the action of centrifugal force. Under the screening effect of first arc sieve and second arc sieve, big cement material granule is detained between first arc sieve and the interior disc of ring mill groove, and medium cement material granule is detained between first arc sieve and second arc sieve, and little cement material granule is detained between second arc sieve and the outer disc of ring mill groove.

Then, the pressurizing mechanism acts and drives the conical grinding roller to move downwards through the rotating column, the bushing moves downwards along with the conical grinding roller and can be in frictional contact with the annular lining disc, and the bushing extrudes the corresponding first arc-shaped sieve plate and the second arc-shaped sieve plate to the position where the annular lining disc is coplanar. Because the grinding disc body drives first arc sieve and second arc sieve rotatory, the fillet of first arc sieve and second arc sieve will be extruded to the bush so, and first arc sieve and second arc sieve are extruded downstream, and first arc sieve and second arc sieve make the arc slider move down, and first arc guide block and second arc guide block follow the motion of arc slider, and first spring and second spring are compressed. When the first arc-shaped sieve plate is extruded downwards, the end surface of one end of the first arc-shaped sieve plate, which is far away from the arc-shaped sliding block, and the upper disc surface of the annular lining disc are in a coplanar state; after the second arc-shaped sieve plate is extruded downwards, when the end face of one end, far away from the arc-shaped slide block, of the second arc-shaped sieve plate and the upper disc surface of the annular lining disc are in a coplanar state, the arc-shaped slide block moves downwards to a position where the end face of the second arc-shaped sieve plate is in contact with the bottom groove surface of the arc-shaped slide block sliding groove, and the arc-shaped slide block cannot move downwards continuously at the moment. Just so can guarantee the bush at the in-process with annular bushing plate mutual extrusion crocus, the upper surface of annular bushing plate forms a flat quotation that does not have the cell surface, and the cement material on the annular bushing plate can not be extruded the second sieve slip of annular bushing plate and lead to the groove and first sieve slip is led to the groove in, the bush of being convenient for can better cooperate the crocus with annular bushing plate. After a set of first arc sieve and second arc sieve extruded by the bush, first arc sieve and second arc sieve extruded before no longer receive the extrusion of bush, under the reset action of first spring and second spring, first arc guide block and second arc guide block make the arc slider remove and reset to the home position, first arc sieve and second arc sieve rebound to the home position, and the screening of first arc sieve and second arc sieve continues to screen the cement material.

The lining cover is pushed down with first arc sieve and second arc sieve back, and the cement granule that first arc sieve of bush crocus and second arc sieve department were screened out is extruded each other to the bush and lining dish. Because the conical grinding roller and the lining are in a conical state, and the diameter of the outer conical surface of the front conical end of the conical grinding roller is smaller than that of the outer conical surface of the rear conical end of the conical grinding roller, the diameter of the outer conical surface of the lining positioned at the front conical end of the conical grinding roller is smaller than that of the outer conical surface positioned at the rear conical lining end of the conical grinding roller. In the mutual matching and grinding process of the bushing and the annular lining disc, the front end part of the bushing extrudes large cement material particles retained between the inner circular surfaces of the first arc-shaped sieve plate and the annular grinding groove, the middle end part of the bushing extrudes medium cement material particles retained between the first arc-shaped sieve plate and the second arc-shaped sieve plate, and the rear end part of the bushing extrudes small cement material particles retained between the second arc-shaped sieve plate and the outer circular surface of the annular grinding groove. The design can enable the lining to better extrude cement materials with different grain sizes, and the lining can simultaneously extrude small cement material grains, medium cement material grains and large cement material grains, thereby improving the efficiency of crushing the cement materials with different grain sizes; in the process of crushing cement materials by the conical grinding roller, the vibration generated by particle crushing is determined by the particle crushing condition, and because the conical grinding roller applies pressure to large, medium and small cement material particles simultaneously, the vibration generated after the large cement material particles are crushed is inhibited by the small cement material particle crushing condition, so that the vibration of the conical grinding roller is determined by the small cement particle crushing condition, and further the sound energy and heat energy loss generated by the vibration of the conical grinding roller are determined by the small cement particle crushing condition. Compare in cylindrical grinding roller crocus cement material granule, cylindrical grinding roller crocus needs to extrude breakage into medium cement material granule with big cement material granule earlier, then cylindrical grinding roller again with medium cement material granule extrusion breakage into little cement material granule, so cylindrical grinding roller vibrations are basically decided by the broken condition of big cement material granule to the acoustic energy and the heat energy loss that cylindrical grinding roller vibrations produced are basically decided by the broken condition of big cement material granule. Because the sound energy and heat energy loss generated by the vibration of the conical grinding roller are determined by the crushing of small cement particles, the sound energy and heat energy loss generated by the vibration of the cylindrical grinding roller are basically determined by the crushing condition of large cement material particles, and the vibration amplitude of the grinding roller is far smaller than the vibration amplitude of the grinding roller due to the crushing of the large cement material particles due to the crushing of the small cement particles, the loss of the conical grinding roller with the design matching of the first arc-shaped sieve plate and the second arc-shaped sieve plate is smaller than that of the cylindrical grinding roller.

In the process that the first arc-shaped sieve plate and the second arc-shaped sieve plate are pressed downwards, when the first supporting block is opposite to the corresponding first square sieve pore on the first arc-shaped sieve plate, the first supporting block on the first arc-shaped supporting plate is quickly inserted into the corresponding first square sieve pore under the reset action of the first plate spring; when the second supporting block is opposite to the corresponding second square sieve pore position on the second arc-shaped sieve plate, the second supporting block on the second arc-shaped supporting plate is quickly inserted into the corresponding second square sieve pore under the reset action of the second plate spring. After first arc sieve is extrudeed downwards, when the one end terminal surface that arc slider was kept away from to first arc sieve reached coplanar with the annular lining dish on the quotation, first supporting block can laminate mutually with the roof face of corresponding first party sieve mesh, and first supporting block just can play the supporting role to first arc sieve like this, avoids first party sieve mesh to produce after receiving too big holding down force and warp. After the second arc-shaped sieve plate is downwards extruded, when the end face of one end, far away from the arc-shaped sliding block, of the second arc-shaped sieve plate and the upper disc surface of the annular lining disc reach a coplanar state, the second supporting block can be attached to the top wall surface of the corresponding second square sieve hole, so that the second supporting block can support the second arc-shaped sieve plate, and the second square sieve hole is prevented from being deformed after being subjected to overlarge downward pressure. The first arc-shaped support plate and the related structures, the second arc-shaped support plate and the related structures are not arranged on the grinding disc body at the upper end of the arc-shaped sliding groove, so that the problem that the strength is reduced after the first arc-shaped support plate, the related structures, the second arc-shaped support plate and the related structures are arranged in the groove of the grinding disc body at the upper end of the arc-shaped sliding groove is solved, and the grinding disc body at the upper end of the arc-shaped sliding groove is difficult to bear the strong downward pressure from the conical grinding roller after the groove is formed. The first arc-shaped supporting plate and the related structure are positioned on the grinding disc body between the first sieve plate sliding groove and the inner circular surface of the annular grinding groove, the second arc-shaped supporting plate and the related structure are positioned on the grinding disc body between the second sieve plate sliding groove and the outer circular surface of the annular grinding groove, and the strength borne by the grinding disc body at the two positions after grooving is obviously higher than that borne by the grinding disc body at the upper end of the arc-shaped sliding block sliding groove after grooving; therefore, under the condition that the first square sieve holes and the second square sieve holes are not deformed after being subjected to overlarge downward pressure, the first arc-shaped supporting plates and the related structures are arranged in the grinding disc body between the first sieve plate sliding groove and the inner circular surface of the annular grinding groove, and the second arc-shaped supporting plates and the related structures are arranged in the grinding disc body between the second sieve plate sliding groove and the outer circular surface of the annular grinding groove.

After the conical grinding roller stops working, the driving mechanism and the pressurizing mechanism stop working, the grinding disc body stops rotating, the conical grinding roller and the lining return to the original position under the driving of the pressurizing mechanism, the conical grinding roller and the lining do not extrude the annular lining disc any more, and the first arc-shaped sieve plate and the second arc-shaped sieve plate are not extruded by the lining any more. After the first arc-shaped sieve plate and the second arc-shaped sieve plate are not extruded by the bushings any longer, under the reset action of the first spring and the second spring, the first arc-shaped guide block and the second arc-shaped guide block enable the arc-shaped sliding block to move and reset to the original position, and the first arc-shaped sieve plate and the second arc-shaped sieve plate move upwards to the original position. In the process that the first arc-shaped sieve plate and the second arc-shaped sieve plate move upwards and reset, the bottom wall surface of a first square sieve pore on the first arc-shaped sieve plate can extrude the inclined surface of the first supporting block, so that the first supporting block drives the first arc-shaped supporting plate to move towards the direction of the first plate spring under the extrusion force of the first supporting block, and the first plate spring is compressed until the first supporting block is completely extruded to be separated from the first square sieve pore; the inclined plane of second supporting shoe can be extruded to the diapire face of the second square sieve mesh on the second arc sieve board, so the second supporting shoe under the extrusion force, the second supporting shoe drives second arc backup pad and removes to second leaf spring direction, and the second leaf spring is compressed, breaks away from out the second square sieve mesh until the second supporting shoe is extruded completely.

Compared with the traditional grinding disc technology, the method has the advantages that the large cement material particles are retained between the first arc-shaped sieve plate and the inner circular surface of the annular grinding groove by utilizing the screening effect of the first arc-shaped sieve plate and the second arc-shaped sieve plate, the medium cement material particles are retained between the first arc-shaped sieve plate and the second arc-shaped sieve plate, and the small cement material particles are retained between the second arc-shaped sieve plate and the outer circular surface of the annular grinding groove; the design of cement granule screening can make the bush extrude the cement material of the different particle sizes of crocus better, and the bush can extrude little cement material granule, medium cement material granule and big cement material granule simultaneously to the efficiency of the cement material of broken different size granules has been improved. In addition, compared with the sound energy and heat energy loss generated by the vibration of the cylindrical grinding roller, the sound energy and heat energy loss generated by the vibration of the conical grinding roller is determined by the crushing of small cement particles, and the crushing of the small cement particles ensures that the vibration amplitude of the grinding roller is far smaller than that of the grinding roller caused by the crushing of large cement material particles, so that the loss of the conical grinding roller with the design matching of the first arc-shaped sieve plate and the second arc-shaped sieve plate is smaller than that of the cylindrical grinding roller. The conical grinding roller with the first arc-shaped sieve plate and the second arc-shaped sieve plate which are designed and matched can reduce the part of electric energy converted into sound energy and heat energy in the grinding process, thereby achieving the effect of energy conservation. In order to ensure that the first square sieve holes and the second square sieve holes do not deform after being stressed by strong downward force, the invention also designs the effect of supporting the first arc-shaped sieve plate and the second arc-shaped sieve plate by utilizing the first supporting block and the second supporting block respectively. The invention has simple structure and better practical effect.

as shown in fig. 18 and 21, a plurality of second supporting blocks 32 are uniformly distributed on the outer arc surface of the second arc-shaped supporting plate 29; the lower surface of each second supporting block 32 is a slope 42;

One end of the supporting turntable 5, which is far away from the grinding turntable body 6, is connected with a driving mechanism. Then, after the driving mechanism acts, the driving mechanism drives the grinding disc body 6 to rotate through the supporting turntable 5.

The end of the rotary column 3 far away from the conical grinding roller 2 is connected with a pressurizing mechanism. Then, when the pressurizing mechanism is actuated, the pressurizing mechanism drives the conical grinding roll 2 to move downwards through the rotary column 3, and the lining 1 can be in frictional contact with the annular lining disc 18.

As shown in fig. 17, the two side corners of the end of the first arc-shaped screen plate 22 away from the arc-shaped sliding block 23 are rounded corners 40. In such a design, in order to facilitate the rotation process of the first arc-shaped sieve plate 22 driven by the grinding disc body 6, the rounded corners 40 on two sides of one end of the first arc-shaped sieve plate 22 far away from the arc-shaped sliding block 23 can be better in pressing contact with the bushing 1, so that the abrasion in the pressing process is reduced.

As shown in fig. 18, the two side corners of the end of the second arc-shaped screen plate 21 away from the arc-shaped sliding block 23 are rounded corners 40. In such a design, in order to facilitate the rotation process of the second arc-shaped sieve plate 21 driven by the grinding disc body 6, the rounded corners 40 on two sides of one end of the second arc-shaped sieve plate 21 far away from the arc-shaped sliding block 23 can be better in pressing contact with the bushing 1, so that the abrasion in the pressing process is reduced.

As shown in fig. 17 and 22, the end of the first support block 37 away from the first arc-shaped support plate 36 has a rounded corner 40; this design facilitates better access of the first support blocks 37 to the respective first square mesh 35. As shown in fig. 18 and 21, an end of the second supporting block 32 away from the second arc-shaped supporting plate 29 has a rounded corner 40; this design facilitates better access of the second support blocs 32 to the corresponding second square holes 30.

As shown in fig. 8, the distance between two adjacent first arc-shaped screen plates 22 is smaller than the distance between two side wall surfaces of the first screen holes. Such a design ensures that the size of the cement material particles allowed to pass through the gaps between two adjacent first arc-shaped sieve plates 22 is smaller than that of the cement material particles allowed to pass through the first sieve holes, so that the sizes of the cement material particles passing through the gaps between two adjacent first arc-shaped sieve plates 22 and the first sieve holes can be maintained to meet the design requirements.

As shown in fig. 3 and 4, the first spring 26 and the second spring 28 are both compression springs; when the first spring 26 and the second spring 28 are not compressed, the first arc-shaped guide block 25 is located at the top end of the first arc-shaped guide groove 8, the second arc-shaped guide block 27 is located at the top end of the second arc-shaped guide groove 9, one end, far away from the arc-shaped sliding block 23, of the first arc-shaped sieve plate 22 extends out of the first sieve plate sliding through groove 16, the first square sieve hole 35 is located on the disc surface of the annular lining disc 18, one end, far away from the arc-shaped sliding block 23, of the second arc-shaped sieve plate 21 extends out of the second sieve plate sliding through groove 15, and the second square sieve hole 30 is located on.

As shown in fig. 14 and 17, the distance between the top wall surface of the first square sieve hole 35 and the end surface of the first arc-shaped sieve plate 22 far away from the arc-shaped sliding block 23 is D1, as shown in fig. 5, the distance between the top groove surface of the first arc-shaped sliding groove 13 and the disc surface on the annular lining disc 18 is D2, and D1 is equal to D2; such design guarantees, after first arc sieve 22 is extrudeed downwards, when the disc face reached coplane state on first arc sieve 22 kept away from the one end terminal surface of arc slider 23 and annular bushing 18, first supporting block 37 inserted in corresponding first party sieve hole 35, first supporting block 37 can laminate mutually with the roof face of corresponding first party sieve hole 35, first supporting block 37 just can play the supporting role to first arc sieve 22 like this, avoid first party sieve hole 35 to produce after receiving too big downforce and warp. As shown in fig. 13 and 18, the distance between the top wall surface of the second square screen hole 30 and the end surface of the second arc-shaped screen plate 21 far away from the arc-shaped sliding block 23 is D3, as shown in fig. 5, the distance between the top groove surface of the second arc-shaped sliding groove 14 and the disc surface on the annular lining disc 18 is D4, and D3 is equal to D4. Such design guarantees that, after the second arc sieve plate 21 is pushed downwards, when the end face of one end of the second arc sieve plate 21 far away from the arc slide block 23 and the disc surface on the annular liner disc 18 reach the coplanar state, the second support block 32 is inserted into the corresponding second square sieve hole 30, the second support block 32 can be attached to the top wall surface of the corresponding second square sieve hole 30, so that the second support block 32 can support the second arc sieve plate 21, and the second square sieve hole 30 is prevented from deforming after being subjected to an excessive downward pressure.

As shown in fig. 17, when the first support blocks 37 on the first arc-shaped support plates 36 contact the intrados of the first arc-shaped screen deck 22 not provided with the first square screen holes 35, the first plate springs 39 are in a compressed state; as shown in fig. 18, when the second support blocks 32 of the second arc-shaped support plate 29 contact the outer arc surfaces of the second arc-shaped screen deck 21 not opened with the second square screen holes 30, the second plate springs 33 are in a compressed state.

The lining disc and the lining 1 have the effects that after the lining 1 is contacted with the lining disc, under the pressurization of a pressurization mechanism, relatively large pressure exists between the lining 1, and after cement material particles enter the lining 1 and the lining disc, the lining 1 and the lining disc are mutually extruded and matched to grind the cement material particles into powder reaching the standard. In addition, the lining disc and the lining 1 are relatively worn, and can be replaced after being used for a period of time.

For the bush 1 in the grinding roller combination, in the mutual extrusion grinding process of the bush 1 and the lining disc, the grinding disc body 6 drives the lining disc to rotate, so that in the extrusion grinding process, the lining disc can drive the bush 1 to rotate around the axis of the rotary column 3, and the bush 1 drives the conical grinding roller 2 and the rotary column 3 to rotate.

The matching process of the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21 with the lining 1 in the grinding roller combination comprises the following steps: firstly, when the lining 1 in the grinding roller combination does not move downwards and is mutually extruded with the lining disc for grinding powder, the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21 are not pressed downwards; at this time, the first spring 26 and the second spring 28 are not compressed, the first arc-shaped guide block 25 is located at the top end of the first arc-shaped guide groove 8, the second arc-shaped guide block 27 is located at the top end of the second arc-shaped guide groove 9, one end, far away from the arc-shaped sliding block 23, of the first arc-shaped sieve plate 22 extends out of the first sieve plate sliding through groove 16, the first square sieve hole 35 is located on the disc surface of the annular lining disc 18, one end, far away from the arc-shaped sliding block 23, of the second arc-shaped sieve plate 21 extends out of the second sieve plate sliding through groove 15, and the second square sieve hole. Secondly, in the process of mutually extruding and grinding the powder by the lining 1 and the lining disc in the grinding roller combination, as the grinding disc body 6 drives the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21 to rotate, the lining 1 can extrude the fillet 40 of the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21, the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21 are extruded to move downwards, the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21 enable the arc-shaped sliding block 23 to move downwards, the first arc-shaped guide block 25 and the second arc-shaped guide block 27 follow the arc-shaped sliding block 23 to move, and the first spring 26 and the second spring 28 are compressed. Thirdly, when the first arc-shaped sieve plate 22 is pressed downwards, the end surface of one end of the first arc-shaped sieve plate 22 far away from the arc-shaped sliding block 23 and the disc surface on the annular lining disc 18 reach a coplanar state; after the second arc-shaped sieve plate 21 is pressed downwards, when the end surface of one end of the second arc-shaped sieve plate 21, which is far away from the arc-shaped sliding block 23, and the upper disk surface of the annular lining disk 18 are in a coplanar state, the arc-shaped sliding block 23 moves downwards to a position where the end surface is in contact with the bottom groove surface of the arc-shaped sliding block sliding groove 7, and at the moment, the arc-shaped sliding block 23 cannot move downwards continuously. Fourthly, after the first and second arc-shaped screen plates 22 and 21 are no longer pressed by the bushing 1, the first and second arc-shaped guide blocks 25 and 27 move the arc-shaped sliding blocks 23 to return to the original position and the first and second arc-shaped screen plates 22 and 21 move upward to the original position under the return action of the first and second springs 26 and 28.

The size of the first square mesh 35 is larger than that of the second square mesh 30: the cement material particles fall to the middle position of the grinding disc body 6, then the rotary grinding disc body 6 drives the cement material particles to rotate, and the cement material particles move to the periphery of the grinding disc body 6 under the action of centrifugal force. At the in-process of cement material granule to the peripheral motion of mill disk body 6, big cement material granule fails to pass through first party sieve mesh 35, and medium cement material granule and little cement material granule pass through first party sieve mesh 35, but medium cement material granule fails to pass through second square sieve mesh 30, and little cement material granule can pass through second square sieve mesh 30. In summary, under the screening of the first arc-shaped screen deck 22 and the second arc-shaped screen deck 21, large cement material particles are retained between the first arc-shaped screen deck 22 and the inner circumferential surface of the ring mill groove 17, medium cement material particles are retained between the first arc-shaped screen deck 22 and the second arc-shaped screen deck 21, and small cement material particles are retained between the second arc-shaped screen deck 21 and the outer circumferential surface of the ring mill groove 17.

One end of each of the two support columns 24 is fixedly arranged on the top groove surface of the arc-shaped sliding block sliding groove 7, and the other end of each of the two support columns passes through the two column holes 41 in the arc-shaped sliding block 23 and is fixedly arranged on the bottom groove surface of the arc-shaped sliding block sliding groove 7; the design is that the arc-shaped sliding block 23 can slide on the supporting column 24; in addition, the supporting column 24 can well support the grinding disc body 6 on the upper part of the arc-shaped sliding block sliding groove 7, and the grinding disc body 6 on the upper part of the arc-shaped sliding block sliding groove 7 is prevented from deforming under heavy pressure.

The first support block 37 on the first arc-shaped support plate 36 and the inclined plane 42 on the first support block 37 are matched with the first square sieve hole 35 on the first arc-shaped sieve plate 22; the flow of the cooperation between the second support blocks 32 on the second arc-shaped support plate 29 and the inclined planes 42 on the second support blocks 32 and the second square screen holes 30 on the second arc-shaped screen plate 21 is as follows: firstly, when the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 are not pressed down, the first supporting block 37 on the first arc-shaped supporting plate 36 is in contact with the inner arc surface of the first arc-shaped screen plate 22, which is not provided with the first square screen hole 35, and the first plate spring 39 is in a compressed state; the second support blocks 32 on the second arc-shaped support plate 29 are in contact with the outer arc surfaces of the second arc-shaped sieve plates 21 which are not provided with the second square sieve holes 30, and the second plate springs 33 are in a compressed state. Secondly, in the process that the first arc-shaped screen plates 22 and the second arc-shaped screen plates 21 are pressed downwards, when the first supporting blocks 37 are opposite to the corresponding first square screen holes 35 on the first arc-shaped screen plates 22, under the reset action of the first plate springs 39, the first supporting blocks 37 on the first arc-shaped supporting plates 36 are quickly inserted into the corresponding first square screen holes 35; when the second supporting blocks 32 are opposite to the corresponding second square holes 30 on the second arc-shaped screen plate 21, the second supporting blocks 32 on the second arc-shaped supporting plates 29 are quickly inserted into the corresponding second square holes 30 under the resetting action of the second plate springs 33. Thirdly, in the process that the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 move upwards to reset, the bottom wall surface of the first square screen hole 35 on the first arc-shaped screen plate 22 can press the inclined surface 42 of the first support block 37, so that under the pressing force of the first support block 37, the first support block 37 drives the first arc-shaped support plate 36 to move towards the first plate spring 39, and the first plate spring 39 is compressed until the first support block 37 is completely pressed to be separated from the first square screen hole 35; the bottom wall surface of the second square screen hole 30 on the second arc-shaped screen plate 21 will press the inclined surface 42 of the second supporting block 32, so that the second supporting block 32 drives the second arc-shaped supporting plate 29 to move towards the second plate spring 33 under the pressing force, and the second plate spring 33 is compressed until the second supporting block 32 is completely pressed to be separated from the second square screen hole 30.

The first arc-shaped sliding groove 13 in the invention can completely meet the condition that the first supporting block 37 in the first arc-shaped supporting plate 36 extends out of the first arc-shaped sliding groove 13. The second arc-shaped sliding groove 14 can completely meet the condition that the second supporting block 32 in the second arc-shaped supporting plate 29 extends out of the second arc-shaped sliding groove 14.

For the first expansion plate 38: the first expansion plate 38 expands and contracts in the moving process of the first arc-shaped support plate 36, the moving track of the first arc-shaped support plate 36 is limited by the first expansion plate 38, and the first support block 37 is prevented from being difficult to enter the corresponding first square sieve hole 35 due to the fact that the first arc-shaped support plate 36 shakes. For the second expansion plate 34: the second expansion plate 34 expands and contracts in the moving process of the second arc-shaped support plate 29, the second expansion plate 34 limits the moving track of the second arc-shaped support plate 29, and the second support block 32 is prevented from being difficult to enter the corresponding second square screen hole 30 due to the fact that the second arc-shaped support plate 29 shakes.

The specific implementation mode is as follows: when the vertical grinding disc of the invention does not work, the grinding roller combination is positioned at the upper side of the grinding disc body 6, and the lining 1 in the grinding roller combination is not contacted with the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21; first spring 26 and second spring 28 are both uncompressed, first arc guide block 25 is located the top of first arc guide slot 8, second arc guide block 27 is located the top of second arc guide slot 9, the one end that arc slider 23 was kept away from to first arc sieve plate 22 stretches out first sieve board sliding through groove 16 and first square sieve hole 35 is located on the dish face is slipped to annular set 18, the one end that arc slider 23 was kept away from to second arc sieve plate 21 stretches out second sieve board sliding through groove 15 and second square sieve hole 30 is located on the dish face is slipped to annular set 18. The first support block 37 on the first arc-shaped support plate 36 is in contact with the inner arc surface of the first arc-shaped sieve plate 22 without the first square sieve hole 35, and the first plate spring 39 is in a compressed state; the second support blocks 32 on the second arc-shaped support plate 29 are in contact with the outer arc surfaces of the second arc-shaped sieve plates 21 which are not provided with the second square sieve holes 30, and the second plate springs 33 are in a compressed state.

In the working process of the conical grinding roller 2, the diameter of the outer conical surface of the conical grinding roller 2 close to the middle of the grinding disc body 6 is smaller than that of the outer conical surface of the conical grinding roller 2 close to the outer circular surface of the grinding disc body 6, the conical end of the conical grinding roller 2 close to the middle of the grinding disc body 6 is a front conical end, and the conical end of the conical grinding roller 2 close to the outer circular surface of the grinding disc body 6 is a rear conical end. That is, the diameter of the outer conical surface of the front conical end of the conical grinding roll 2 is smaller than the diameter of the outer conical surface of the rear conical end of the conical grinding roll 2.

When the vertical grinding disc of the invention grinds cement materials, the driving mechanism acts and drives the grinding disc body 6 and the annular lining disc 18 to rotate through the supporting turntable 5; subsequently, the material conveying mechanism on the upper side of the grinding disc body 6 drops the cement materials at the middle position of the grinding disc body 6, then the rotating grinding disc body 6 drives the cement material particles to rotate, and the cement material particles move to the periphery of the grinding disc body 6 under the action of centrifugal force. Under the screening effect of first arc sieve plate 22 and second arc sieve plate 21, big cement material granule is detained between first arc sieve plate 22 and the interior disc of ring mill groove 17, and medium cement material granule is detained between first arc sieve plate 22 and second arc sieve plate 21, and little cement material granule is detained between second arc sieve plate 21 and the outer disc of ring mill groove 17.

Then, the pressurizing mechanism acts and drives the conical grinding roller 2 to move downwards through the rotary column 3, the bushing 1 moves downwards along with the conical grinding roller 2, the bushing 1 can be in frictional contact with the annular lining disc 18, and the bushing 1 presses the corresponding first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21 to the position where the annular lining disc 18 is coplanar. Since the grinding table body 6 rotates the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21, the bushing 1 presses the round corner 40 of the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21, the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 are pressed to move downwards, the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 cause the arc-shaped sliding block 23 to move downwards, the first arc-shaped guide block 25 and the second arc-shaped guide block 27 follow the movement of the arc-shaped sliding block 23, and the first spring 26 and the second spring 28 are compressed. When the first arc-shaped sieve plate 22 is pressed downwards, the end surface of one end of the first arc-shaped sieve plate 22, which is far away from the arc-shaped sliding block 23, and the disc surface on the annular lining disc 18 reach a coplanar state; after the second arc-shaped sieve plate 21 is pressed downwards, when the end surface of one end of the second arc-shaped sieve plate 21, which is far away from the arc-shaped sliding block 23, and the upper disk surface of the annular lining disk 18 are in a coplanar state, the arc-shaped sliding block 23 moves downwards to a position where the end surface is in contact with the bottom groove surface of the arc-shaped sliding block sliding groove 7, and at the moment, the arc-shaped sliding block 23 cannot move downwards continuously. Just so can guarantee that bush 1 is at the in-process with annular bushing disc 18 mutual extrusion crocus, the upper surface of annular bushing disc 18 forms a flat quotation that does not have the cell surface, and the cement material on the annular bushing disc 18 can not be extruded in the second sieve slip logical groove 15 and the first sieve slip logical groove 16 of annular bushing disc 18, and the bush 1 of being convenient for can better cooperate the crocus with annular bushing disc 18. After the bushing 1 presses the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 of the next group, the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 which are pressed before are not pressed by the bushing 1 any more, under the reset action of the first spring 26 and the second spring 28, the first arc-shaped guide block 25 and the second arc-shaped guide block 27 enable the arc-shaped slide block 23 to move and reset to the original position, the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 move upwards to the original position, and the screening of the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 continues to screen cement materials.

After the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21 are extruded downwards by the bushing 1, the bushing 1 and the lining disc mutually extrude and grind cement particles screened at the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21. Because the conical grinding roller 2 and the lining 1 are in a conical state, and the diameter of the outer conical surface of the front conical end of the conical grinding roller 2 is smaller than that of the outer conical surface of the rear conical end of the conical grinding roller 2, the diameter of the outer conical surface of the lining 1 positioned at the front conical end of the conical grinding roller 2 is smaller than that of the outer conical surface of the rear conical lining 1 positioned at the conical grinding roller 2. As shown in fig. 23, in the process of milling by the mutual cooperation of the liner 1 and the annular liner disk 18, the front end portion of the liner 1 presses large cement material particles retained between the first arc-shaped screen plate 22 and the inner circumferential surface of the annular milling groove 17, the middle end portion of the liner 1 presses medium cement material particles retained between the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21, and the rear end portion of the liner 1 presses small cement material particles retained between the second arc-shaped screen plate 21 and the outer circumferential surface of the annular milling groove 17. By the design, cement materials with different grain sizes can be better extruded and milled by the lining 1, and small cement material grains, medium cement material grains and large cement material grains can be simultaneously extruded by the lining 1, so that the efficiency of crushing the cement materials with different grain sizes is improved; in the process of crushing cement materials by the conical grinding roller 2, the vibration generated by particle crushing is determined by the particle crushing condition, and because the conical grinding roller 2 applies pressure to large, medium and small cement material particles at the same time, the vibration generated after the large cement material particles are crushed is inhibited by the small cement material particle crushing condition, so that the vibration of the conical grinding roller 2 is determined by the small cement particle crushing condition, and further the sound energy and heat energy loss generated by the vibration of the conical grinding roller 2 are determined by the small cement particle crushing condition. Compare in cylindrical grinding roller crocus cement material granule, cylindrical grinding roller crocus needs to extrude breakage into medium cement material granule with big cement material granule earlier, then cylindrical grinding roller again with medium cement material granule extrusion breakage into little cement material granule, so cylindrical grinding roller vibrations are basically decided by the broken condition of big cement material granule to the acoustic energy and the heat energy loss that cylindrical grinding roller vibrations produced are basically decided by the broken condition of big cement material granule. Since the losses of acoustic and thermal energy generated by the vibrations of the conical grating roll 2 are determined by the crushing of small cement particles, the losses of acoustic and thermal energy generated by the vibrations of the cylindrical grating roll are substantially determined by the crushing of large cement material particles, while the crushing of small cement particles causes the vibrations of the grating roll to have a much smaller amplitude than the crushing of large cement material particles, the losses of the conical grating roll 2 with the first arched screen deck 22 and the second arched screen deck 21 designed to cooperate are smaller than the losses of the cylindrical grating roll.

In the process that the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 are pressed downwards, when the first supporting blocks 37 are opposite to the corresponding first square screen holes 35 on the first arc-shaped screen plate 22, under the reset action of the first plate spring 39, the first supporting blocks 37 on the first arc-shaped supporting plate 36 are quickly inserted into the corresponding first square screen holes 35; when the second supporting blocks 32 are opposite to the corresponding second square holes 30 on the second arc-shaped screen plate 21, the second supporting blocks 32 on the second arc-shaped supporting plates 29 are quickly inserted into the corresponding second square holes 30 under the resetting action of the second plate springs 33. After first arc sieve plate 22 is pushed down, when the one end terminal surface that arc slider 23 was kept away from to first arc sieve plate 22 reached coplane state with the dish face on annular bushing 18, first supporting block 37 can laminate mutually with the roof face of corresponding first party's sieve mesh 35, and first supporting block 37 just can play the supporting role to first arc sieve plate 22 like this, avoids first party's sieve mesh 35 to produce after receiving too big holding down force and warp. After the second arc-shaped sieve plate 21 is extruded downwards, when the end face of one end of the second arc-shaped sieve plate 21, which is far away from the arc-shaped sliding block 23, and the disc surface on the annular liner disc 18 reach a coplanar state, the second supporting block 32 can be attached to the top wall surface of the corresponding second square sieve hole 30, so that the second supporting block 32 can support the second arc-shaped sieve plate 21, and the second square sieve hole 30 is prevented from being deformed after being subjected to an excessive downward pressure. The first arc-shaped support plate 36 and related structures, the second arc-shaped support plate 29 and related structures are not arranged on the grinding disc body 6 at the upper end of the arc-shaped sliding block groove 7, so that the problem that the strength is reduced after the first arc-shaped support plate 36 and related structures, the second arc-shaped support plate 29 and related structures are arranged on the grinding disc body 6 at the upper end of the arc-shaped sliding block groove 7 in a groove mode is solved, and the grinding disc body 6 at the upper end of the arc-shaped sliding block groove 7 is difficult to bear the strong downward pressure from the conical grinding roller 2 after the groove is formed. The first arc-shaped supporting plate 36 and related structures are positioned on the grinding disc body 6 between the inner circular surfaces of the first sieve plate sliding groove 12 and the annular grinding groove 17, the second arc-shaped supporting plate 29 and related structures are positioned on the grinding disc body 6 between the outer circular surfaces of the second sieve plate sliding groove 10 and the annular grinding groove 17, and the strength borne by the grinding disc body 6 at the two positions after slotting is obviously higher than that borne by the grinding disc body 6 at the upper end of the arc-shaped sliding block sliding groove 7 after slotting; it is more advantageous to have the first arched support plate 36 and related structures mounted in the disc body 6 between the first screen sliding groove 12 and the inner circumferential surface of the ring groove 17 and the second arched support plate 29 and related structures mounted in the disc body 6 between the second screen sliding groove 10 and the outer circumferential surface of the ring groove 17, while ensuring that the first square mesh 35 and the second square mesh 30 are not deformed when subjected to excessive downward pressure.

After the conical grinding roller 2 stops working, the driving mechanism and the pressurizing mechanism stop working, the grinding disc body 6 stops rotating, the conical grinding roller 2 and the lining 1 return to the original position under the driving of the pressurizing mechanism, the conical grinding roller 2 and the lining 1 do not extrude the annular lining disc 18 any more, and the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 are not extruded by the lining 1 any more. When the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 are not pressed by the bushing 1 any more, the first arc-shaped guide block 25 and the second arc-shaped guide block 27 cause the arc slide block 23 to move and return to the original position under the return action of the first spring 26 and the second spring 28, and the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 move upward to the original position. In the process that the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21 move upwards to reset, the bottom wall surface of the first square screen hole 35 on the first arc-shaped screen plate 22 can press the inclined surface 42 of the first support block 37, so that under the pressing force of the first support block 37, the first support block 37 drives the first arc-shaped support plate 36 to move towards the first plate spring 39, and the first plate spring 39 is compressed until the first support block 37 is completely pressed to be separated from the first square screen hole 35; the bottom wall surface of the second square screen hole 30 on the second arc-shaped screen plate 21 will press the inclined surface 42 of the second supporting block 32, so that the second supporting block 32 drives the second arc-shaped supporting plate 29 to move towards the second plate spring 33 under the pressing force, and the second plate spring 33 is compressed until the second supporting block 32 is completely pressed to be separated from the second square screen hole 30.

In conclusion, the invention has the main beneficial effects that: according to the invention, by utilizing the screening effect of the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21, large cement material particles are retained between the first arc-shaped screen plate 22 and the inner circular surface of the annular grinding groove 17, medium cement material particles are retained between the first arc-shaped screen plate 22 and the second arc-shaped screen plate 21, and small cement material particles are retained between the second arc-shaped screen plate 21 and the outer circular surface of the annular grinding groove 17; the design of cement granule screening can make bush 1 extrude the cement material of the different particle sizes of crocus better, and bush 1 can extrude little cement material granule, medium cement material granule and big cement material granule simultaneously to the efficiency of the cement material of broken different size granule has been improved. In addition, the acoustic and thermal energy losses due to the vibrations of the conical grinding roll 2 are determined by the breaking of small cement particles, which in turn causes the grinding roll to vibrate to a much smaller extent than the breaking of large cement material particles, compared to the acoustic and thermal energy losses due to the vibrations of a cylindrical grinding roll, so that the losses of a conical grinding roll 2 with a first arched screen deck 22 and a second arched screen deck 21 designed to cooperate are smaller than the losses of a cylindrical grinding roll. The conical grinding roller 2 with the first arc-shaped sieve plate 22 and the second arc-shaped sieve plate 21 in matching design can reduce the part of electric energy converted into sound energy and heat energy in the grinding process, thereby achieving the effect of energy conservation. In order to ensure that the first square screen holes 35 and the second square screen holes 30 are not deformed after being subjected to strong downward pressure, the invention also designs that the first supporting blocks 37 and the second supporting blocks 32 respectively play a role of supporting the first arc-shaped screen plates 22 and the second arc-shaped screen plates 21. The invention has simple structure and better practical effect.
