GMDs: the driving force behind sustainable mill operations
Gearless mill drives (GMDs) constitute a compelling alternative to traditional ring-geared mill drives (RMDs) in such environments. Both drive types can be used to power large semi-autogenous (SAG), ball and autogenous mills, but GMDs are proven to offer superior availability, uptime and efficiency. When the first GMD was developed by …
