SAG Milling in Australia -Revised Submission

2014-10-1  The CCV – ring motor (gearless) drive is used at Cadia (20 MW) and Olympic Dam (18 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

Mill drive selection for semiautogenous grinding mills

2019-11-14  mill. However, recent SAG mill designs now include a single pinion drive that is used to transmit 5.6 MPa (7500 hp) to a mill. Consequently, it is now possible, with a twin pinion drive, to have power transmission delivering I 1.8 MPa (15,000 hp) to a mill. This power level is now approaching that available through the gearless drive system ...
