Abstract
AbstractMicromechanical 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. The simulations are likened with a previously conducted one‐way coupling. Furthermore, the rotor speed is varied to identify its influence on stress energy and number of contacts. Using the stress energy distribution and the measured fracture distribution, an effective dispersion fraction can be calculated and correlated with the dispersion progress.
