  • 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.
