Increasing the effective volume of the ball mill can increase the efficiency of the mill production. Ordinary alloy linings are thick and heavy, which reduces the effective volume of the mill and increases the power consumption, which reduces the production efficiency of the ball mill. Therefore, the material of the lining is very important.

In order for the ball mill to perform normal grinding operations, its working speed must be less than the critical speed. Ball mills generally work in a “dropped” state. There are many working speeds to achieve this working state, but there must be the most favorable working speed. 1. If the rotating speed is low, the ball in the ball mill
