power based sag mill design calculations. 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.
