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.
