The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 4045%. If it is a grate discharge you will have more flexibility of the total charge. Ball size and ball grade is determined by the feed ore size and hardness, plus the PH level of the slurry.

of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semiautogenous and ball mills which is based on the motion of grinding charge inside the mill.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size.
