Difference between a Cement Ball Mill and Vertical Cement Mill

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 ...
