Ball mill speed can be reduced during short maintenance measures, e.g. inspections of the SAG mill. This avoids fixed speed pinion drives have to be stopped with a prior grinding-out / drain-out process before interruption and the necessary time to restart. As a consequence, variable-speed capability helps the operator to reduce downtime.
