Abstract

Stirred bead mills used in industry allow to split up particules in suspension by agitating a milling medium. The multiple impacts may damage beads and thus reduce the stirred milling process efficiency. A discrete numerical approach including simple fluid effects is proposed and carried out in this paper to model and study finely the damage phenomenon. The simulation data allow to identify internal variables of the milling medium and to localize high energy zones. The order of magnitude of contact forces including fluid contribution will enhance the bead wear law.
