The effect of particle size on the breakage rates of a number of
materials is illustrated in Fig. 7. The coarsest particle size simulated
was limited to 7.9 mm, since the validity of the simulations using
the mechanistic ball mill model becomes questionable as particle
size increases, given assumption (i) in the model. Fig. 7 reproduces
the well-documented trend of breakage rates with particle size,
with an increase in breakage rates up to a maximum, at a particle
size of about 1–4 mm, following by a drop at coarser sizes for the
different materials. Simulated results, represented using symbols,
were used in fitting parameters of the equation proposed by Austin
