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.
SAG grinding mill with a stockpile in the background. The now smaller materials are fed to screens that size ore, resulting in minerals less than 1.3 cm (½ in) to fall through the screens. The screening process. The smaller ore will go on to the ball grinding mills where they will be further ground down.
