Optimizing your SAG mill operationInternational Mining. 2007 3 21 The optimal performance of AG/SAG mills is the key to successful plant operation All AG/SAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as slurry and pebble pooling which decrease throughput and increase energy consumption.
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.
