Industrial SAG mills use steel balls together with the coarse particles for particle size reduction (Gupta and Yan, 2006). One of the key variables in grinding performance is the residence time distribution (RTD) of the different phases inside the mill (e.g. liquid, ore, media). RTD is important because it explains the mixing regime as well as ...
