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.
