Ball Mill

The Description and Function of Ball Mill：

Ball mill is the key equipment for recrushing the materials after they are primarily crushed. Ball mill is widely used for the dry type or wet type grinding of all kinds of ores and other grindable materials in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry.

The Inner Structure and Main Types of Ball Mill:

Ball mill is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control. According the materials and discharging method, ball mill can be divided into dry type ball mill and wet type lattice ball mill.

Ball mill is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control. The hollow shaft uses steel casting, the inner lining can be dismantled and changed, and the rotary rack wheel uses casting gear hobbing and inside the cylinder there is wear-resisting lining board which has fine abrasion performance. This machine has stable operation and reliable performance.

According the materials and discharging method, ball mill can be divided into dry type ball mill and wet type lattice ball mill.

This machine is a horizontal type cylinder rotary device and outside the cylinder there is drive gear which drives the cylinder to rotate during the working process. Materials spirally and evenly go into the first cabin of the grinding machine through the feeding hollow shaft from the feeding device, and inside the first cabin, there are ladder lining boards or ripple lining board in which there are many steel balls with different specifications. The cylinder rotates and produces eccentric force to bring the steel balls to a certain height, and then the steel balls will fall down to impact and grind the materials. After being coarsely ground in the first cabin, the materials will go through the single-layer partition board and into the secondary cabin in which there are flat lining board, and in the lining board there are steel balls to further grind the materials. Finally the powdery materials will be discharged from the discharging grating bar to complete the powder grinding process.
