Charge inside a SAG mill with steel liners. If the mill were released from its maximum "non-zero energy state", the mill can roll back and accelerate to speeds an order of magnitude larger than inching speeds (1 to 3 RPM). Hand calculations verify these numbers. When charge load in the mill is centered, it is in "zero energy state". ...

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).

SAG-mill Power Index® (SPI) Test. The SPI® test is carried out in a standardised mill under set conditions, with the output being the time to reach a given size, which can be converted to a SAG mill specific energy input (in kWh/t). The SPI® index provides a profile of the hardness of the ore type and can be used for geometallurgical models.
