Mill (grinding) - Wikipedia
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.

AG Autogenous Grinding - Mineral Processing & Metallurgy
In autogenous mills the diameter is greater than the length. They can be as much as 40+ feet in diameter. Patented in 1959, AG Mills are not so popular any more. This large diameter of mill is required to achieve the impact necessary to grind the ore. The main source of reduction comes from the impact of the rock falling on rock.

SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. To help the process along, eight-inch-diameter steel balls are added to the rocks as they tumble inside the rotating mill (semi-autogenous — gets some help from the steel balls).
