How to improve working efficiency of ball mill

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.
