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.

Ball mill shell is a large steel part made of steel plate. Different specifications of steel balls are added into the shell cylinder. When the ball mill is working, the steel balls rotates with the shell under the action of friction force and inertia force. The material contained in the ball mill is crushed and finely ground by gravity. 1.
