these models has not been evaluated The purpose of this investigation is to determine if liberation can be changed by mill operating parameters It is hoped that this work can be used as a precursor to the development of a model that can predict liberation given the various ranges of operating parameters Mill speed mill charge ball size

of the Bond ball mill grindability test For all model based methods a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw Morrell (1996) proposed a mathematical model for autogenous semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill

A major advance in the modeling of ball mills became possible through the development of the discrete element method DEM provides a numerical procedure for solving Newton's second law with an appropriate contact relationship that can be applied to describe the motion of each grinding medium contained in the mill charge to predict element position velocity and forces of interaction over time
