Mill (grinding) Wikipedia. SAG is an acronym for SemiAutogenous Grinding. SAG mills are autogenous mills but 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'' () in diameter, powered by a 28 MW (38,000 HP) motor.
In SAG mills, the rock grinding media is complemented with a small proportion (3–20% of mill volume) of steel balls (with diameter of ~ 120–150 mm). The steel ball media in an SAG mill changes the nature of the mill performance considerably compared to an AG mill. The additional charge weight due to steel media in an SAG mill must be ...
