8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.

Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where Dm = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.

Ball End Mills Ball end mills or "ball nose end mills" are used for making full radiused grooves, generating large corner radii, or contour profile milling. General purpose ball end mills, with a 30° helix, are available in many diameter sizes and lengths.
