sag mill make use of steel balls included with some large and hard rocks for grinding. these mills utilize the balls in making the large fragments of materials broken into pieces. the ball charge of a sag mill is about 9% to 20%.this process takes place inside the large rotating drum of sag mill which is filled with balls partially.
sag mill itself and not on the test work program. stated another way money invested in a large sag mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates.
