Mill (grinding)

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.

Using Abrasion Index for calculating Steel Balls and mill

Also we observe for SAG mills that ore competence and feed size distribution, being major influence on rock to steel ratio in the mill, are significant factors that influence SAG mill steel wear. We've observed the abrasion index to be a less useful means of predicting SAG mill grinding media wear.
