Relations between the mill operational and design variables were defined using the perfect mixing modelling approach for wet ball mill grinding systems [13]. Operational and design parameters were related to mill model parameter which was defined by a ratio of breakage rate (r) to discharge rate (d) function and identified by r/d.
