The performance of our device is sufficiently …

Ball Mill Explained - saVRee

As the ball mill rotates, the balls 'stick' to the inner surface of the drum due to the centrifugal force created within the drum. At a certain angle, the weight of the balls overcomes the centrifugal force holding them against the drum and they begin to tumble back to the centre line of the ball mill (this area is known as the ' toe ').
