BrainWave is ideally suited to stabilize the operation of SAG mills. Effective grinding in a SAG mill depends largely on how it is loaded. A mill containing too much material does not allow for adequate movement of the ore and balls. A mill that does not contain enough material does not take advantage of the autogenous grinding mechanism.
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.
