Grain-Based DEM for Particle Bed Comminution

The comminution at the grain size level for liberating valuable minerals usually requires highest size-specific energy. Therefore, a full understanding of process this is essential. Models based on Discrete Element Method (DEM) can become helpful tool purpose. One major concern, however, missing representativeness mineral microstructures in simulations. In study, method to overcome limitation presented. authors show how realistic microstructure be implemented into particle bed simulation using grain-based models DEM (GBM-DEM). improved algorithm-based modeling approach exemplarily compared an equivalent real experiment. simulated results obtained within presented study that it possible reproduce interfacial breakage observed experiments level. This particular interest as aim processing not only reduction coarse particles, but often efficient liberation components. Simulations with automatically generated will help further improve efficiency ore processing.
