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.

The energy consumption of a ball mill is typically very high, especially in the startup phase. This is due to the high power requirements of the mill motor, and the need to heat the grinding media and the material being ground to a high temperature. On the other hand, a vertical cement mill operates with lower energy consumption, mainly due to ...
