We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The loading or change volume can then be read off the graph below or
SAG mills of comparable size but containing say 0 ball charge in addition to the rocks , normally, operate between 70 and 75 of the critical speed. Dry Aerofall mills are run at about 85 of the critical speed. The breakage of particles depends on the speed of rotation. Working with a 7.32 m diameter and 3.66 m long mill, NapierMunn et al. 4 observed that the breakage rate for the finer size fractions of

Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge. Frictional wear or rubbing forces act on the particles, as well as collision energy. These forces are derived from the rotational motion of the balls and movement of particles within the mill and contact zones of colliding balls. By rotation of the mill body, due to friction between mill wall and balls,
