By this summer, a grinding mill that is bigger around than a Boeing 747 will turn chunks of copper ore into gravel-sized bits for smelting and refining. The largest ring gear will make it happen
Pictures of the insides of an AG mill and a SAG mill which have been crash stopped are shown in Figures 5 and 6 respectively. Accurate measurements of the ball filling can only be made after the mill is ground out. In this case the mill is operated with the feed turned off until all of the ore has exited the mill.

The clutch's primary role on the dual-pinion, direct-drive geared mill is to provide smooth starts during mill startup. When the mill is running, the clutch also serves as a torque "circuit breaker," reducing costly repairs and downtime by protecting the pinions and ring gear from potential damage caused by large pieces of grinding material.

History. The SAG mill model by proposed by Leonard Austin (1990) was largely based on modifications of earlier tumbling mill models by Hogg & Fuerstenau and F. Bond. The model uses a kinetic-potential energy balance to describe the power draw of a mill charge. Many geometric components of the earlier models were fit to empirical relationships measured by Austin.
Both the SAG mill and ball mill are each driven by two gear units. Because, on a conventional drive variant, only one engagement per pinion with the girth gear is possible per side, an economic power limit of about 8 MW per drive is in effect. With the DMG2 gear units, Siemens said this limit expands to as much as 12 MW per drive.
