The performance improvement of a full-scale autogenous

Oct 20, 2020· The strategy of direct addition large lumps of ore results in a significant improvement in the performance of a full-scale autogenous mill. A nearly 40% reduction in the mill power consumption, and a nearly 30% increase in the mill throughput can be achieved by increasing the percentage of materials larger than 200 mm in the mill feed from less

Mill (grinding) Wikipedia

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
