Ball Mill Working principle: When the ball mill works, motor and speed reducer transmit torque force to big and small gears of ball mill, so the barrel rotates. When the barrel rotates, Steel balls or other grinding media in the barrel are lifted to a certain height and fall down freely, so materials in the barrel are impacted. Grinding

Ball Mill Media and Operations. Solids loading is another variable that is critical to optimal mill performance. The principle of mill operation is the impingement of the solids between pieces of media. The majority of media motion and milling occurs on the surface of the bed of media where the media is cascading. If there are
