Working with a m diameter and m long mill, NapierMunn et al. [4] observed that the breakage rate for the finer size fractions of ore (say mm) at lower speeds (, 55% of the critical speed) was higher than that observed at higher speeds (, 70% of the critical speed). For larger sizes of ore (in excess of 10 mm), the breakage rate was lower for mills rotating at 55% of the ...
