Chat OnlineApr 01, 1999 Apr 01, 1999 The calculated power draft is maximum at about 50% ball load. According to Eq. 1, mill power is a function of ball mass (M b) and the distance between mill center and the center of gravity of ball mass (r g). So, as the mill filling increases M b goes up, but r g decreases. Therefore, the power draft passes through a maximum.
