If it is also assumed that the mean overall values of S i for a mixture of balls is the weighted mean of S i values for each ball size, equations are derived for calculating this mean value. As an example, the results are used in a mill simulation to show the quantitative effect of different ball mixes in a two-compartment cement mill versus a uniform mix over the whole mill.
