  • Mineral and Mining Engineering: What is the working principle of

    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
