The ball mill grinding experimental results and simulation results showed that they were fairly consistent with each other. The simulation of higher speed mills such as pin type stirrers has been extensively investigated for relatively small-scale applications by JKSimMet. In this study, the JKSimMet software package was adapted for a stirred mill with the help of the base model of ball milling.

Simulation 4 included changes adopted in Simulation 3, along with (a) reducing the SAG mill ball diameter from 5" to 4", (b) reducing the ball mill ball diameter from 2.5" to 2" and (c) increasing the ball charge in the ball mills from 27.5% to 30%. All these modifications aimed to increase the energy consumption in both SAG and two ball mills, which would thus be converted into a higher
