Difference Between Sag Mill vs Ball Mill - mech4study
Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness.

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%.[6][7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.[8]
