With a higher density mill charge. 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.VIBRA-DRUM® Grinding Mill & Crushing Mill General Kinematics,The VIBRA-DRUM® Grinding Mill has very few moving parts. A VIBRA-DRUM® Grinding Mill does not require the typical massive concrete foundation required of a conventional rotary grinding mill unit. Structural steel supports are designed as an integral part of the VIBRA-DRUM® Grinding Mill and simply bolted to a suitable load-bearing floor.
