Multi-Component AG/SAG mill model structure. According to the preliminary modelling findings, the breakage rates for each component vary according to their proportion in the mill fresh feed. The reason behind this variation is that different feed blends result in different compositions in the mill charge, which act as grinding media.
The model of the mill is a combined model consisting of a charge modelled with DEM and the mill structure modelled with FEM. The non-linear finite element code LS-Dyna v971 (2007) has been used for the modelling and simulation of the mill.
Therefore, a new multi-component AG/SAG mill model structure was developed to account for these observed effects, and it was validated using …
