Increasing Availability Through Advanced Gearless Drive

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.
