Ball Mill - an overview ScienceDirect Topics
The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.

A ball mill is a type of grinding equipment used to finely grind materials. Many balls, referred to as media, are placed into the mill with the material to be ground, and the mill is rotated. The material is finely ground by collision forces among the material, balls, and mill wall. Operation time depends on
