ball mill filling degree formula
Ball Millsan 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.
