Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the,Slurry flow in mills: grate-pulp lifter discharge systems,,01/07/2003· The mill used for the testwork program was 1 m in diameter and 0.5 m long. Power was delivered from a 18.5 kW motor via a variable speed gearbox which provided a speed range of 7–42 rpm. Feed to the mill was supplied by a steady-head tank.
