However, if we now look at industrial mills, which could have as much as 8 m in diameter, for instance, we would run out of memory (>10 GB) if we include particles with a minimum size of 28 mm, which are just about the coarsest size present in the mill, if we use the same ball and particle size distributions!

Abstract Modelling the pulp fluid and its interaction with both the charge and the mill structure is an interesting challenge The interaction is normally modelled with a combination of CFD and DEM, where the DEM particles (grinding balls) create the structure through which the fluid penetrates, and in its turn creates forces on the grinding balls
