Ball Size Distribution. As the mill starts grinding action and throughput increases. However after reaching a critical speed the mill charge clings to the inside perimeter of the mill. Under this conditions the grinding rate is significant reduced or stopped. All mills must operate less than Critical Speed

In Grinding selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often the ball used in ball mills is oversize "just in case".
