Dynamics of Balls and Liquid in a Ball Mill - Temple Math

This means that the balls are lifted up in layers with distance of twice the radius of a ball and with the angular velocity of the mill. We can do so because the first layer is lifted up by the steel bars with the angular velocity of the cylinder and the other layers are pressed to the outer layers and so they cannot slide down and are.
