Grinding experiments on the sieved-size fraction of silica sand in a planetary ball mill were carried out. It was confirmed that the breakage of a relatively fine size fraction by large balls in the mill can be described by the first-order law, but the law breaks down when the ball size is too small. The reasons for this abnormal breakage were experimentally investigated and the relationship between the ball size and the critical size of material was given in this paper. For the normal breakage, the specific rate of breakage of materials was described by the equation Si = axiαQ(z), where Q(z] is the probability function ranging from 1 to 0, which has been used by Austin in a tumbling ball mill. In this equation, S has a maximum value, and the particle size of the maximum can be related to the ball size by xm = 0.05dB, that is, a 20: 1 ball diameter/particle size ratio gives the optimum condition for the planetary milling. This optimum condition is the same as that in a stirred ball mill, but different from tumbling ball milling and vibration ball milling. Finally, the effect of the diameter and the density of balls on the breakage was expressed by the form a = k3(pB /dB0.35).
