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.
multistream plants, where mill liner design and selection is only tackled on a cost consumables basis. However, the gains to be had through good liner design and selection are just as great as on the large SAG mills. This paper looks at recognising problems in liner design and selection in existing operations.

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.
The Telfer Train 1 SAG Mill Operational data was collected for a six week prior to the installation of the Manta Cube. Four sets of SAG mill operational data are graphed as histograms in Figure 10. These are, 1. The SAG mill speed (rpm) 2. The SAG mill power (MW) 3. The SAG mill feed rate (tph) 4. The SAG mill weight (tonnes) Figure 10.
