Abstract. Micromechanical aggregate properties are correlated with stress conditions during the dispersion process in a stirred-media mill. The fracture energy distribution of the aggregates measured via micro-compression tests is compared with the stress energy distribution in a stirred-media mill determined by CFD-discrete element method simulations and by an analytical model.
describes progress in developing CFD modelling for a Netzsch horizontal bead mill. This mill was chosen because it follows a commonly-used design, and in addition some experimental data has been obtained for this mill which may be used for comparison with CFD predictions.

DEM (Discrete Element Method) is a powerful tool in predicting particle behaviour, which is ideal for the study of stirred media milling. The CFD (Computational Fluid Dynamics) is used to model the motion of slurry by numerically solving the Navier–Stokes equations facilitated with the Volume of Fluid (VOF) and multiphase flow models.
