Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process.

SAG 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.

By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the disadvantage of not controlling the top size of feed

If you have SAG "dry" application, where % of moisture in the ore is very, very low and the charge is fluidized with ventilated air, I would say the chance of packing is very small. Then again, packing of shell liners will have major effect on the charge motion, while packing of F/E liners, shouldn''t compromise grinding too much other than reducing available volume.

However, the SAG route is more power-intensive and, for very hard ores, comes with some process risk in predicting performance. More recently, a hybrid solution has become available in the form of high pressure grinding rolls (HPGRs), which can replace the third stage of crushing and also the SAG mill.
