DetailsSAG 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.
DetailsEarly SAG mills had a diameter of about 32', later increasing to 34, 36, 38 and 40'. At the same time the mill volume also increased. Typically a SAG mill has a much larger diameter compared to its length. Yet the SAG mill of Newmont's Yanacocha mine in Peru is a single stage mill (no ball mill after the SAG mill) and

DetailsThe crushed pebbles fall directly onto the SAG mill feed belt and return to the SAG mill. SAG mill product feeds two parallel ball mills of 6.6 m×11.1 m (internal diameter×length), each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed.
DetailsSingle stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
DetailsThe SAG mill feed conveyor transfers the crushed ore into the SAG mill for grinding. The SAG mill reduces the ore size to the consistency of coarse gravel, using a wet-grinding process. Discharge from the SAG mill is significantly wet and has the consistency of slurry. The slurry is discharged through a screen to remove any oversized material.
