3 size reduction - SlideShare

The load of balls in a ball or tube mill is normally such that when the mill is stopped, the balls occupy about one-half the volume of the mill. The void fraction in the mass of balls, when at rest, is typically 0.40. When the mill is rotated, the balls are picked up by the mill wall and carried nearly to the top, where they break contact with ...
