SAG is an acronym for semiautogenous 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' () in diameter, powered by a 28 MW (38,000 HP) motor.

Ball mills work well on hard, brittle materials. They are not as suitable for grinding elastic, ductile or fibrous materials, or for fine grinding in general. Ball mills can blend and grind at the same time, yielding a fine, intimate mixture. Conventional ball mills are usually limited to a particle size of 1µ after one hour of grinding
