Worlds largest geared drive 2x8500kW Wushan, China (operating) Among the many reasons that geared drives on large SAG mills are not favoured, is due to not having an efficient variable speed drive option (60 to 80% critical speed), which is required for process reasons.
ABB has successfully commissioned three variable-speed mill drive systems at Thompson Creek Metals Mount Milligan copper/gold mine in Canada.. ABBs delivery included one gearless mill drive system (GMD) for a 40-ft-diameter (12.2-m) semi-autogenous (SAG) mill and two low-speed, dual-pinion, ring-geared mill drive systems (RMDs) for two 26-ft (8-m) ball mills.
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.
