Siemens supplied and commissioned direct-drive systems for belt conveyor and grinding mills located 4,200 meters above sea level. The motor size is not limited by the gearbox size, thus eliminating the need for multi-motor drives.
With successful operation of 2 x 6.5MW (Phu Kham, Laos) and three 2 x 7MW units under manufacture (Pascu Lama) and a further 40 projects worldwide, energy efficient Hyper Synchronous SER drives are now mature and ready for use on 2 X 10MW dual drive mills. Speed variation required is in the range of +/- 15% of synchronous motor speeds.
Grinding represents a crucial process step in ore processing – for the overall perfor-mance of a mine. That's why the gearless drive of a grinding mill is the crucial piece of equipment in the concentrator – and why it is subject to very high demands. High availability and reliability through-out the entire lifecycle are a must, while
