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.
