DEM modeling of ball mills with experimental

Discrete element method simulations of a 1:5-scale laboratory ball mill are presented in this paper to study the influence of the contact parameters on the charge motion and the power draw. The position density limit is introduced as an efficient mathematical tool to describe and to compare the macroscopic charge motion in different scenarios, i.a. with different values of the contact parameters.

CFD‐Discrete Element Method Simulations Combined

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.
