The represents a section of a mill in operation. The power input required to maintain this condition is theoretically: hp = (W) (C) (Sin a) (2π) (N) where W = weight of charge. C = distance of center of gravity or charge from center of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in rpm.

The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases (Concha et al. 1992; Katubilwa and Moys, 2009; Erdem and Ergun, 2009).
