The main difference between these two mills is the use of steel balls as grinding media, typically in the order of 612% in volume (Sbarbaro et al., 2005), in the SAG mills. With the addition of grinding media, the SAG mill has shown to be more flexible in operations than AG mills, since it allows the economic treatment of a wider variety of ...

4 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).
