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' .
ball charge., but not less than 18% of the total volume." This states that AG mills are designed at 18% ball safety, mills operating at maximum 12% balls get 6% ball safety, while operations at maximum 18% get 3% ball safety. The original statement was that all mills should be designed at 3% ball safety over their maximum operating load.
