### 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. A SAG mill with a 44 (13.4m Once the basic operating conditions have been defined for the mill designer then and only then can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of any grinding mill. They must carry the load of the shell assembly

The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the (8) Marcy 6 x 6 x2 x 8 dia Tricone Ball Mills with a Westinghouse 500 HP Synchronous Motor 2 300volts 327rpm Ball Mills include rubber liners.

The SAG mill pinion energy is determined from the SAGDesign™ testwork results as follows W SDT = revs (16 000 m s)) / (447.3 m s) where W SDT = AG/SAG Specific Pinion Energy from a F 80 of 152.4 mm to a T 80 of 1.7 mm kWh/ton ground revs = Cumulative number of SAG test mill revolutions to 80 passing 1.7mm m s = SAG mill feed sample mill and there is nothing to prevent a 1 1 aspect ratio mill of say 10 m dia. x 10 m EGL equipped with a 20 MW motor from being fabricated. Such a mill would have a less arduous environment than say a 13.4 m (44-ft) diameter mill. Slurry transport issues then dominate the mill selection rather than mechanical/structural constraints.
