Controlling the volumetric filling in the mill is necessary to optimize the mill's throughput rate. Traditionally, volumetric filling has been inferred by controlling to a total mill weight either from bearing pressure or load cells. However, the mill weight is destabilized by two factors, decreasing liner mass and changing charge density.
