CALCULATION OF THE POWER DRAW OF DRY .

given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semiautogenous and ball mills which is based on the motion of grinding charge inside the mill. He also verified his approach with various plant data (NapierMunn et. al., 1996). In this study, power draw of 14 multi ...
