Differences between Cement Ball Mill and Vertical Cement Mill Grinding Mechanism. The grinding mechanism of a ball mill is a series of impact and attrition events that occur inside a large rotating drum. The grinding media collide with each other and the material being ground in the drum, creating a large amount of heat.

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.
