Ball Mill Working Principle
Ball Mill Motor drives the rotary cylinder through the rotation of reducer and surrounding large gear or it directly drives the cylinder with the rotation of surrounding large gear. The body of cylinder has installed appropriate grinding media - grinding mill balls or steel bars. They are raised to a certain height by centrifugal force and friction, and then fall down with the falling down or drain off state. Grinded materials are continuously given to the cylinder from the mouth, and then crushed by the movement of the grinding media. Finally, the materials will be discharged by the strength of overflow and continuous ore feeding so as to move to the next step.


Ball Grinding Mill Machine Advantages
