However, in this paper, comminution efficiencies are based on the comparison of ball milling with single-particle comminution, either in terms of the energy to produce new surface or in terms of some size distribution parameter. If the energy to produce new surface by single-particle breakage is used as the basis for evaluating efficiency, then the efficiency of ball milling has a more ... power calculation formula for ball mill,

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.
