A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically …
Based on previous investigations of ultrafine comminution in planetary ball mills, a new centrifugal mill has been developed which permits similar high stress conditions. Because this new type of mill is equipped with an immobile chamber, devices for measuring energy, for cooling the milling vessel, as well as, in continuous operation, …

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 ').
When the ball mill rotates at a certain speed, the grinding medium such as steel ball (rod) or gravel in the cylinder rises to a certain height with the rotation of the cylinder under the action of its own gravity, the friction between the cylinder liner and the centrifugal force generated by the rotation of the ball mill.
