A Novel Particle-Based Approach for Modeling a Wet Vertical Stirred Media Mill

Modeling of wet stirred media mill processes is challenging since it requires the simultaneous modeling complex multiphysics in interactions between grinding media, moving internal agitator elements, and fluid. In present study, a model an HIG5 pilot vertical with nominal power 7.5 kW developed. The based on particle-based coupled solver approach, where fluid modeled particle finite element method (PFEM), are discrete (DEM), structure (FEM). different constituents treated by loose (or weak) two-way couplings PFEM, DEM, FEM models. Both water mineral slurry used as fluids, they Newtonian non-Newtonian respectively. work, novel approach for transferring forces Reynolds number implemented. This force transfer realized specifying drag coefficient function number. to predict consumption, dynamics both interparticle contacts wear development structure. numerical results obtained within study show good agreement experimental measurements.
