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 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

To examine the dependence of critical rotation speed on ballcontaining fraction, we measured critical speeds at various ballcontaining fractions from to stepped by Since at lower fraction than we could not observe the centrifugal motion, we chose this fraction range. A jar of ballmill consists of a cylinder and two lids.
