The first drive motor 36 and the second drive motor 37 are responsible for providing power.
The working principle is as follows:
when chemical raw materials are ground, large chemical raw materials are firstly ground by a rough grinding roller 28 and then divided into smaller chemical raw materials, then the chemical raw materials are ground by a fine grinding roller 29, the chemical raw materials which accord with the screening diameter after being ground by the rough grinding roller 28 can fall into a material storage cavity 2 through a second screen 7, the chemical raw materials which accord with the screening diameter after being ground by the fine grinding roller 29 can fall into the material storage cavity 2 through a first screen 5, then the chemical raw materials which do not accord with the screening standard after being ground by the fine grinding roller 29 fall onto a circular plate 3, a rotating motor 21 is started, a moving block 20 moves towards the direction far away from a feed inlet 9, the rotating motor 21 stops working after the moving block 20 moves to the farthest position, a telescopic cylinder 23 extends to move a movable end, a push plate 24 is driven to press on the circular plate 3, then the rotating motor 21 rotates reversely to drive the push plate 24 to move, in the process, the push plate 24 pushes the raw materials on the circular plate 3, simultaneously push pedal 24 strikes off grinding case 1 inner wall, when moving to the position that is close to feed inlet 9, rotating electrical machines 21 stop motion, telescopic cylinder 23 withdraws the expansion end, push pedal 24 no longer oppresses ring plate 3, under vibrating spring 33's effect, ring plate 3 drives first screen cloth 5 and second screen cloth 7 and takes place the vibration, the industrial chemicals who gets into feed back pipe 8 by feed inlet 9 is under the effect of hollow shaft 12 and blade 13, industrial chemicals constantly rolls at the promotion in-process, the industrial chemicals who accords with the screening condition gets into in cavity 15 by feed port 14, and finally get into and deposit in the material chamber 2, the industrial chemicals who is not conform to the screening condition is led to coarse grinding roller 28 by discharging pipe 11 and is ground again.
