The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).

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 3035% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.
