  It is obviously well understood that autogenous AG and semi-autogenous SAG mills operate quite differently from conventional rod mill or ball mills. Since these mills are of a grate discharge type they operate with varying loads with the power drawn by the mill being dependent upon the volumetric load within the mill and factors that influence the viscosity of the charge as shown in Figure
