behavior of large Ring Motors for grinding mills 3 1 Introduction The mining industry uses grinding mills to comminute tonnage. Large grinding mills are driven by Gearless Drives, with the Ring Motor as its main component. The Ring Motor is wrapped around the mill and its rotor poles installed at an extension of the mill head.
Mill (grinding) Wikipedia. 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.
