Crushed ore is fed to the ball mill through the inlet a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills the ball mill is charged to approximately 33 with balls (range 30-45 ). Pulp (crushed ore and water) fills another 15 of the drum s volume so that the total volume of the drum is 50 charged.

    keep the balls climbing up the wall of the mill then tumbling down. If the mill goes too fast called "centrifuging " centrifugal force just holds the balls against the outside of the mill and they don t tumble hence don t do any grinding or mixing.
