Why Determination Of Critical Speed Of A Ball Mill Is Important

The point at which the mill becomes a centrifuge is called the critical speed. The critical speed of the ball mill usually refers to the critical speed of the ball mill. The critical speed of the ball mill actually refers to the speed that the centrifugal force at the shell of the ball mill equals to the gravity, and the critical speed is more important in size.
