Apr 16, 2015 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 SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG SAG milling can often be accomplished with fewer lines than in a conventional rod mill ball mill.SAG mills with a rated power of up to 35 MW. As well as ever larger SAG mills, ball mills are also expanding in size. In the late 1990s the trend moved towards using GMDs to power these larger ball mills, as well as using the drive to vary the speed. GMDs quickly moved from 20’ ball mills, expanding to 24, 25 and then 26’ mills. In early.SAG mills of comparable size but containing say 10 ball charge (in addition to the rocks), normally, operate between 70 and 75 of the critical speed. A ball mill is an effective means of dispersing solid materials in solids or liquids. 8, 9 Ball mills have several advantages which include versatility, low cost of labor and maintenance.
