Coupled CFD-DEM simulation of pin-type wet stirred media mills …

The grinding beads and slurry are agitated by a high-speed stirrer, resulting in the collisions of grinding beads with one another and with the mill internals. These collisions drive the breakage phenomenon or the particle size reduction in the slurry, if the product particles are caught in between the collision partners.
