Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...

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.

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
