    The SAG mill model in the JKSimMet software has not been shown to accurately reproduce the performance of a single stage mill for greenfield design. A review of most modern power models shows that the prediction of specific energy is influenced by the high energy breakage characteristics of the ore (DWi t 10 SPI etc.) and the low energy (BWi).
