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.

8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles ...

Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in ...

Autogenous grinding tests were run in a 10-ft x 4-ft Rockcyl mill. The principle of prepared feed and media was utilized to determine how coarse a feed could be commercially fed to a rock mill. Secondary rock milling was expanded toward the particle sizes of primary milling while still utilizing the practices of secondary milling.

9.1. Introduction. Disintegration and size reduction of some ores is possible in tumbling mills without the aid of grinding media. Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the grinding media.
