In the one-level discharge bin being formed by discharging grate plate and discharging bin liner plate, be provided with lifting blade.
Beneficial effect: material of the present utility model is ground and added the discharge of two-stage screw discharge by ladder lining board, having reached the material below 1mm can become finished product and enter feed bin, cylindrical shell is discharged, simple in structure, is beneficial to and realizes required technological parameter, take up room little, and discharging is fast, output is large, there will not be putty phenomenon, prevent grinding, improved the production efficiency of grinding machine.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A generalized section in the utility model Fig. 1.
In figure: 1 charging end cap, 2 feed auger pipes, 3 feed end liner plates, 7 cylindrical shells, 8 ladder lining boards, 9 discharging grate plates, 10 discharging bin liner plates, 11 grate plate framves, 12 crusher discharge end covers, 13 discharging spiral pipes, 14 lifting blades.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
Figure 2 shows that A-A generalized section in the utility model Fig. 1.
The utility model comprises cylindrical shell 7, is provided with charging end cap 1, feed auger pipe 2 and feed end liner plate 3 at the feed end of cylindrical shell 7, and feed auger pipe 2 is connected on cylindrical shell 7 by charging end cap 1, and charging aside-liner 3 is installed in charging end cap 1 inner side; Be provided with ladder lining board 8 in cylindrical shell 7 inner sides; Be provided with discharging grate plate 9, discharging bin liner plate 10, grate plate frame 11, lifting blade 14, discharging spiral pipe 13 and crusher discharge end cover 12 at the discharge end of cylindrical shell 7, discharging grate plate 9 is bolted on grate plate frame 11, discharging grate plate 9, grate plate frame 11, discharging bin liner plate 10 are arranged on cylindrical shell 7 inside, discharging grate plate 9 forms one-level discharge bin with discharging bin liner plate 10, and fixing by bolt and crusher discharge end cover 12, crusher discharge end cover 12, discharging spiral pipe 13 are connected with cylindrical shell 7 by bolt.
In the one-level discharge bin being formed by discharging grate plate 9 and discharging bin liner plate 10, be provided with lifting blade 14.
Material enters one-level discharge bin from grinding storehouse through discharging grate plate 9, drive material to enter discharging spiral pipe 13 at one-level discharge bin by the lifting blade 14 of king bolt, enter cylinder sieve part, bulky grain falls into feed bin from slide valve, submitted into powder concentrator and finally screened by bucket, fine powder is brought into feed bin by wind from top.
Be less than 1.0mm particle diameter material and be collected in time for ensureing to meet, the system that grinds mainly takes following mode to carry out particle diameter control: the one, and ball mill outlet particle diameter mainly regulates by the steel ball matching of filling, the 2nd, the gap of grinding machine discharge end grate is controlled, the 3rd, grinding machine goes out material screen mesh size and carries out the control of discharging particle diameter, the 4th, regulate powder concentrator Air Quantity Required, guaranteeing to be less than 1.0mm particle diameter can be sucked and select powder equipment to carry out classification by induced draught system in time.
Grinding machine input and output material portion charging adopts circular tube spiral batcher directly to insert the spiral charging of mill trunnion, and discharging afterbody grate plate adds and enters thickness separator by negative pressure by pipeline after material screen screening and carry out classification.
Because of in grinding process, the size of material particles is successively decreased to mill tail direction, just should become as qualified or have a product that part is qualified to discharging quill shaft place.The size and dimension of abrasive body adapts to therewith, and the size of abrasive body should be successively decreased to mill tail direction.1mm is certified products below, and it is meticulous to be difficult for, and cylindrical shell just can not be long for this reason, and long can to form fine powder ratio excessive, therefore be provided with partition device for barn, rough separates abrasive body by size with shape.The grate plate of partition device for barn has screen analysis effect to material, can prevent that excessive particle from entering the weak section of impulsive force.In partition device for barn, be provided with lifting blade, the material that wind band is not walked, is forced to enter cylinder sieve part by lifting blade, otherwise, broken not material piece certain section in grinding machine is piled up, seriously affect crush efficiency; Or the coarse granule without milled is just discharged outside mill.Require 50 tphs for output, common waveform liner plate is just difficult for reaching requirement, adopts ladder lining board to meet to promote the requirement of steel ball, again can even wearing, make the stable yield of grinding machine.For meeting the requirement of required lifting coefficient of friction, adopt one section of flat liner plate the microcephaly of liner plate.Adopt Archimedes spiral curved surface ladder lining board, first material is by the effective fineness that grinds the material in mill body, the animal of hurricane band step by step that adopts ladder lining board to form is expected mill tail, material enters one-level discharge bin through grate plate coarse fraction, improving drop through lifting blade sends in the discharging spiral-tube in crusher discharge end cover, and utilize the thrust of spiral-tube, and material is discharged, enter drum sieve and sieve.
Material of the present utility model is ground and is added the discharge of two-stage screw discharge by ladder lining board, having reached the material below 1mm can become finished product and enter feed bin, cylindrical shell is discharged, simple in structure, is beneficial to and realizes required technological parameter, take up room little, and discharging is fast, output is large, there will not be putty phenomenon, prevent grinding, improved the production efficiency of grinding machine.
The above-mentioned embodiment of the utility model, just illustrates, and is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all surrounded by the utility model.
