The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A.

The increased mill charge load will lead to an increase in mill power draw. The onset point of overfilling an AG/SAG mill can be indicated when the mill power draw exceeds the safe operation power threshold. In a ball mill however the mill power draw is dominated by ball media charge volume for a given mill rotational speed.
