Dec 01, 2020 grinding of the finer particles within the slurry due to the collisions and shear of the coarser particles (rocks and grinding media), and dispersive transport of these fines within a slurry. in a wet mill. The motion and breakage of the coarser particles within a mill are predicted by the DEM component of the model.
Abstract. A coupled DEM SPH model can be used to predict the motion and breakage of resolved coarser particles within a SAG mill. The fine product from coarse particle fracture can then be included in the slurry phase modelled using SPH. This allows, in principle, the prediction of the breakage and transport of coarser material and the transport of the finer material within the grinding and pulp
