The obvious solution is to use more pinions, say, four per mill, with each pair coupled to the output shafts of a special single-input/double-output reducer — two reducers and two motors per mill. The problems of load division remain in this case, both in the reducers and in the motors. Another solution is to use the so-called "gearless drive."

Austin SAG model - SAGMILLING
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.

What's the Difference Between SAG Mill and Ball Mill ...
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

SAG Mill Grinding Circuit Design - 911metallurgist
SAG mills have a higher installed power density for a given plant footprint relative to AC mills. With the combination of finer grind and a lower installed power density (based on the lower density of the mill charge), a typical AG mill has a lower throughput, a lower power draw, and produces a finer grind.
