Lets calculate/select/pick a new ball for your SAG mill. Now, lets suppose you have a SAG Mill and Ball Mill that are not drawing full kW Power. The SAG Mill has a "small" circulation load of oversize given be the 3/8″ trommel screen and the 1/2″ x 1 1/4″ discharge grates. The load of 4″ balls in this SAG is "good" but un-measured.
Surely its got to do with the feed size and product reduction size required? SAG mills are used predominantly with feed material with a larger max lump sizes (from primary crushing plant typically in the max lump size range 150 mm to 300mm and a psd to follow) and the ball or rod mills are for smaller feed lump sizes.

If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example: the hoisting capacity of the mine shaft is the rate-limiting step in the process, and the SAG mill must adapt to ...
