Simulation of Stress Energy and Grinding Media …

Abstract. Grinding is an important process in the mineral, chemical and pharmaceutical industries. In the last couple of years, the discrete element method (DEM) has become more and more important for modeling different grinding processes and for the calculation of stress mechanism, frequency and intensity.

CFDDiscrete Element Method Simulations Combined …

Micromechanical aggregate properties are correlated with stress conditions during the dispersion process in a stirredmedia mill. The fracture energy distribution of the aggregates measured via microcompression tests is compared with the stress energy distribution in a stirredmedia mill determined by CFDdiscrete element method simulations and by an analytical model.
