Description

The roll-type comminutor

The utility model relates to a kind of to powder raw material, particularly the Granulation Equipments of ceramic raw material.

At present, along with the development of building industry, the designs and varieties of ceramic building material are more and more, and are also more and more higher to the requirement of ceramic raw material.As make ceramics such as artificial granite graininess ceramic raw material in irregular shape just need be provided.And existing pair roller type granulator is to utilize a pair of surface to have the move toward one another of the running roller of relative groove, and the powder that feeds is pressed into agglomerate.The agglomerate that extrudes also need be transported to other crusher in crushing and become needed granularity.Complex process not only, floor space is big, and the particle of making is fine and close inadequately, more easily forms layering and crackle, can not satisfy the needs of ceramic building material well.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of roll-type comminutor binder and broken function and compact product structure that has is provided.

The utility model is achieved in that this roll-type comminutor comprises casing, feed hopper, hopper, transmission device.4 pairs of rollers that are arranged in parallel from top to bottom are housed in casing.Above two pairs be nip rolls, be smooth roll; Below two pairs be breaker roll, wherein drive roll is a smooth roll, driven voller is a rotor.Each does to rotate synchronously in opposite directions to roller.Its course of work is as follows: powder enters first pair of roller compressional zone of time nip rolls one by one through feed hopper, move toward one another with work two smooth rolls, powder is pressed into the powder sheet, breaks away from first pair of roller then and enter second pair of roller-secondary nip rolls, by the smooth roll of move toward one another with the further compacting of powder sheet.Enter the 3rd pair of roller-primary fragmentation roller subsequently, lean on the move toward one another of rotor and smooth roll that the powder sheet is cut into strip.Enter the 4th pair of roller-second-time breakage roller at last, utilize the relative motion of rotor and smooth roll that strip-shaped materials is cut into graininess once more.Like this, just make shape after twice binder of powder this comminutor of process, third fragmentation and differ, the particle of compact structure is outside hopper discharge machine.

Advantage of the present utility model is: this machine is combined as a whole binder and crushing process, thereby has simplified technology, equipment, dwindles floor space, has reduced cost.Simultaneously, the particle of being produced is compact structure not only, and its size, shape can change by the blade distance, the position that change on the rotor, to satisfy various different needs.

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the utility model transmission device schematic diagram;

Fig. 4 is the A enlarged drawing of Fig. 2.

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

With reference to Fig. 1, Fig. 2, Fig. 4, this roll-type comminutor is made up of casing 10, feed hopper 9, hopper 11, transmission device 12 and four pairs of 1,2,3,4,5,6,7,8 of rollers.Four pair roller wound packages from top to bottom are arranged in parallel in casing 10.Above two pairs 1, the 2 and 3, the 4th, nip rolls is ganoid steel bowl.The material scraping plate 16 that the removing sizing is used is housed in the nip rolls bottom.Below two

pairs

5,6 and 7,8 be breaker roll.Drive roll 5,7 is a smooth roll, the topped rubber-like elastic material in roller skin surface.Driven voller 6,8 is a rotor.Rotor 6 is perpendicular cutting roller; Rotor 8 is the crosscut rotor, also can be perpendicular cutting roller.Perpendicular cutting roller is made of the blade 17 that polylith is enclosed within on the axle side by side.For ease of pressing the gap between the product size requirements adjustment blade, blade 17 cooperates with the between centers crack, is provided with packing ring 18 between the blade, reaches the purpose of adjusting play by the thickness of adjusting washer (disk).End at axle is provided with screw thread, by nut 19 packing ring 18 and blade 17 is compressed.For preventing buildup between the blade of perpendicular cutting roller, between blade 17, be provided with rib tooth 14.Shuttle tooth 14 is L-shaped, inserts in the gap between the blade, and shuttle tooth support 15 is fixed on the casing 10.Crosscut rotor 8 is made of the blade 26 that polylith is fixed on the roller, and blade 26 is parallel with axis or angled with axis.Four pairs of beam barrels are equipped with the roller lash adjusting device, are realized by the slide block type spiro rod regulating device 13 that is contained on the driven voller bearing block.

With reference to Fig. 1, Fig. 3, the transmission device 1 of this comminutor comprises two systems: I, two pairs of

nip rolls

1,2,3,4 are power with motor 20, drive driving shaft 24 and rotate behind belt transmission, chain transmission double reduction.2 coaxial sprockets 22,23 are arranged on the driving shaft.Sprocket wheel 22 drives drive roll 1 and rotates behind chain reduction, roller 1 makes driven voller 2 do oppositely to rotate with speed, thereby finishes the first road binder operation through gear drive.In like manner, sprocket wheel 23 also drives another roller 3,4 is done oppositely to rotate with speed behind chain reduction, thereby finishes the second road binder operation.II, two pairs of breaker rolls are power with motor 21, drive drive roll 7 and rotate through the belt transmission back of slowing down, and a sprocket wheel 25 coaxial with roller 7 drives drive roll 5 rotations through chain transmission constant speed.Roller 5 is through gear drive, make the driven voller 6 that perpendicular cutting knife is housed do oppositely to rotate with speed, finish cutting action one time, simultaneously, roller 7 makes the driven voller 8 that revolving knife (or perpendicular cutting knife) is housed do oppositely to rotate with speed through gear drive, finish the secondary cut operation, two pairs of breaker rolls are worked in coordination, and the powder sheet cross-cut with compressing is broken into needed particle.

This roll-type granulator is except as the granulation of ceramic raw material, also can be used for feed processing or use in other industries that need powder is granulated.
