 · The Mt. Mulligan mine produces ore of lowgrade coppergold. It has a capacity to grind approximately 2,717t per hour at 92% availability. The 12m semiautonomous grinding (SAG) mill is powered by a gearless motor drive. The IsaMill machine is used for fine grinding the ore. It is one of the most energy efficient grinding machines on the ...

About 1911, the fully enclosed oil bath gearless mill was patented: one of the first mills ever to offer full mechanical enclosure coupled with self lubriion. In 1916, the double geared oil bath mill was introduce, thereby phasing out the popular open type double crank mill, a bread and butter model that had been in production since 1900 or thereabouts.

ABB gearless mill drive, installed 2002 at the Minera Escondida in Chile. ABB announced that it will supply a new MW gearless mill drive (GMD) system for a 26 ft ball mill, including transformers, ring motor and a complete electrical room entirely equipped, to Minera Escondida/Chile.
