Basic Ball Mill Grinding Circuit

A mill consists of a steel shell supported at each end by a hollow trunnion running in a bearing, lined with steel plates, and driven by belt and gears or by motor and gears. The mill is set at a slight slope and is fed with finely crushed ore and water through one trunnion. When ground fine enough by the load of balls, the pulp is discharged through the other trunnion and run where desired
