In the air got into filter box 61 through going out tuber pipe 43, filter 62 filtered the material powder in the air, then the air moved to the tuber pipe 612 of crossing that is located cooling chamber 711, cooling pump 73 starts to make the coolant liquid in the cooler bin 72 move to cooling chamber 711, the coolant liquid cools off the air that is located tuber pipe 612, then the air moves to cooling fan 42 department through connecting pipe 415 to the cooling effect of cooling fan 42 to the material has been improved.

Pile up the material powder gathering at filter 62 and form blockily, clearance cylinder 65 starts to drive clearance board 66 and removes, and second brush 53 on clearance board 66 clears up filter 62, consequently piles up blocky material on filter 62 and falls to go on in collecting box 63 for the speed that the air passes through filter 62 has been accelerated, thereby has improved the filtration collection effect of air to material powder.

The barrel 2 rotates to drive the first screen 17 to rotate, the first screen 17 rotates to enable the second hairbrush 53 on the cleaning plate 66 to clean the first screen 17, the screening effect of the first screen 17 on materials is accelerated, the production efficiency of the ball mill is improved, meanwhile, the speed of air passing through the first screen 17 is also accelerated, and the cooling effect of the air on the materials is improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
