Ball mills with two different sizes were considered in this study, one small and another large. The simulations with the two mills have the same conditions as the real ones by Valderrama et al. (1996) and Kalala and Moys (2004), respectively, in terms of mill size, particle size, mill speed fraction (mill speed as a fraction of critical speed) and fill level fraction.
