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').

What is Centrifugal Force? (with pictures)

There is untold confusion regarding centrifugal force, yet the concept is very simple. If you swing a ball on a piece of string the ball "exerts" a centrifugal force on you hand, your hand, in its turn, exerts a centripetal force on the ball. You can see from this the ball is "exerting" a centrifugal force, it is not subject to such a force.
