Abstract

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