Ball mill . A ball mill uses steel (or rubber) balls to grind material. A rotating drum carries balls up the rising side of the rotating shell, where they the fall upon the raw material below. Ball millls provide a relatively efficient method of grinding in terms of power requirements, speed of grinding, and capacity for continuous operation.

In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …
