Three types of ballmills were employed to finely mill the prepared samples: a rotary ball mill (RBM), a stirred ball mill (SBM), and a vibratory ball mill (VBM). These mills consist of a grinding chamber filled with different milling media (balls, beads, cylinders.) set in motion by either movement of the chamber or by a rotor.

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, in a tumbling mill, many free surfaces are ...

A coupled SPHDEMFEM model was used by Jonsén et al. (2014) to study the flow of the slurry and the motion of the grinding media in a ball mill, and their interaction with the mill structure. In Jonsén et al. (2015), this modeling approach was validated against experimentally measured driving torque in a labsize ball mill.
