Both drive types can be used to power large semiautogenous (SAG), ball and autogenous mills, but GMDs are proven to offer superior availability, uptime and efficiency. When the first GMD was developed by ABB in the late 1960s, a 5MW mill was considered powerful. Today, modern mines may have multiple 1525MW GMDs running in tandem.
