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. ZGMn13 (high manganese steel) lining is a suitable ...

efficiency of ball mills has focused on the monitoring of the fill level. For a given amount of steel balls, it is not desirable that the mill is too full or too empty of grinding material. If the fill level of ore grinding is low, most of the energy of the steel balls is wasted in impacts between them, leading to low comminution ratios. As the fill level increases, the gaps between the steel ...
