  • The effect of ball size on mill performance ScienceDirect

    The specific rates of breakage of particles in a tumbling ball mill are described by the equation Si = axαi(Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases. This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by xm = k1d2.
