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.). However, SAG mill weight is difficult to control as the dynamic response changes as the mill approaches maximum capacity.
