ABB’s ring-geared mill drive system (RMDplus) offers optimized solutions for grinding applications such as AG, SAG, pebble mills, rod mills and ball mills. These drive system is based on ABB’s ACS drives family and offers all benefits and possibilities such as smooth starting, fast and precise control and network-friendly operation. In addition, functionality like starting torque and current limitation, automatic positioning, creeping speed, frozen charge detection, frozen charge remover, empty mill detection, etc., required for grinding applications is implemented in these mill drives.
The goal of our RMDplus courses is to teach operation and maintenance aspects of a medium voltage RMD with or without control block.
