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.

The type of drive and drive design used on a given mill, especially with respect to the motor type, is directly influenced by the study of the owner's electrical system. Manufacturing limitations from gear vendors determine the minimum number of pinions which can be used to drive the mill as well as the number of gear sections.
