drive application is a dualpinion SAG mill driven by two 5,000 kW wound rotor induction motors (WRIM). Two TMdrive10SPRs control motor speed by recovering rotor current and returning the power to the utility supply. Confi gured in a twin motor arrangement, the motors share load in the tandem mill.

The LCI twin pinion system has found acceptance overseas but has not been installed to date in Australia. The Fimiston m (36 ft) SAG mill uses twin wound rotor/gearbox/ pinion drives with variable speed achieved through CCV systems. The CCV ring motor (gearless) drive is used at Cadia (20 MW) and Olympic Dam (18 MW).

Firstly, there was a serious flaw in the power configuration of the SAG mill and ball mill (both rated at 6000 kW with a single pinion drive). The capacity of the SAG mill was not fully utilized, as the actual operating power draw was only 3358 kW. This meant it was only operating at 56% of its maximum power, providing large room for improvement.
