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.

The mill is designed to handle a total ball charge of 324.5 t at 100 loading with a percentage filling of 29.5 in both the chambers Both the chambers of the cement mill were charged with 80 of the designed charge which works out to 86 t in Ist chamber and 172 t in the IInd chamber.

Also with low ball charge slurry pool will reduce grinding efficiency. Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy. I think at last in this situation, power consumption will increase.
