  • SOPHISTICATED RING GEARED MILL DRIVES FEATURES

     · When talking about ring geared mill drives (RMD s) and especially dual pinion systems (see figure 1) the possibility to add mechanical stress by the motors can be significant. Therefore the control concept between the two motors must be fast and accurate to avoid any additional stress to the pinions and the ring gear.

  • Availability and Reliability Gearless Drives

     · 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.
