Both ring-geared mill drives and GMDs can be employed to drive autogenous, semi-autogenous (SAG) and/or ball mills. The applications may be the same, but the challenge now is to develop bigger drivetrains with the power to drive these larger grinding mills – and this is exactly where GMDs come into their own.
