STEPPING FORWARD USING VARIABLE SPEED DRIVES FOR OPTIMIZING THE GRINDING PROCESS IN SAG AND BALL MILLS *I. Atutxa and I. Legarra . The breakage rate function shape of the SAG mill is largely governed by the mill load particle size distribution and mill speed. The feed in the mill contains fractions of ore that serves as the grinding media.

The Slip Energy Recovery Drive (S.E.R. Drive) is a technology well proven in the industry for large power motoring systems that allows precise motor speed control at the same time that recover the slip energy in the wound rotor induction motors (WRIM). The typical applications include SAG mill, AG mill and ball mill.

MW). It has been the industry standard for SAG mills above 13 MW capacity. However, pinion systems to 8 MW per pinion and dual motor systems with quadruple pinions extend the range of gear driven mills to a theoretical limit of 32 MW. The Ernest Henry SAG mill (11 MW) is currently the largest twin pinion single drive mill installed in Australia.

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod millball circuit. All of the above contributes to
