### What is the difference between a SAG mill and ball mill

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.
