    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.
