Semi-autogenous(sag) mill for grinding solution

SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding large rocks like in a ball mill. SAG mill is generally used as a primary or first stage grinding solution.  It is widely used in the gold, copper and platinum industries but also in the lead, zinc, silver, and nickel industries.

Over the last few years, SAG mill manufacturing technology has advanced rapidly. The bounds of mill size have been pushed from two directions. Firstly, the advent of ring motors has removed the constraint applied by the power that a single pinion gear was able to transmit. Secondly, the development of dual pinions in close proximity, driven from a single motor, has doubled the power that can be applied to a geared drive from twin motors.

Operating techniques, too, have improved markedly. Advances have been made in understanding the effect of feed size on mill capacity, with secondary crushing now commonly adopted for very competent ores. The “Mine-to-Mill” concept has been enthusiastically incorporated, since its introduction in 1998.
