The ball charge and ore charge volume is a variable, subject to what is the target for that operation. 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 40-45%. If it is a grate discharge you will have more flexibility of the total charge.

Grate discharge ball mill
If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.
