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.
Grinding Mills. Barry A. Wills, James A. Finch FRSC, FCIM, P.Eng., in Wills' Mineral Processing Technology (Eighth Edition), 2016 7.1 Introduction. Grinding is the last stage in the comminution process where particles are reduced in size by a combination of impact and abrasion, either dry, or more commonly, in suspension in water.

Semi-autogenous grinding mills (S AG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter.
