Ball mill out in position publication

Apr 14, 2021

A series of batch grinding tests were carried out using three loads of single size media, i.e. 30.6 mm, 38.8 mm, and 49.2 mm. Then two ball mixtures were successively considered. The equilibrium ball mixture was used to investigate the effect of ball size distribution on the selection function whereas the original
