Analysis and modelling of bead contacts in wet

Wet fine grinding is an important unit process in various industries. In the present two different stirred media mills (one with a cylindrical stirrer; one with a disc stirrer) and a planetary ball mill are investigated using coupled CFD (computational fluid dynamics) and DEM (discrete element method) simulations. While the DEM takes the grinding
