Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., Mainza, A.N. 2009).

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.
