An effective sphere-based model for breakage simulation in DEM

نویسندگان

چکیده

Breakage occurs in several particulate systems that are simulated using the discrete element method (DEM), namely crushing and grinding as well inadvertently others include transportation, handling, mixing, separation geotechnical applications. Different approaches may be used to describe particle breakage DEM, but cases which influences significantly flow behaviour of material, imbedding description DEM provides only valid alternative. This study describes implementation a detailed model based on replacement with spheres commercial software EDEM. It accounts for variability size-dependency fracture energies, weakening particles by unsuccessful stressing events, addressing reported shortcomings sphere schemes. The is verified great detail basis single-particle information validated measurements unconfined beds mineral ores.
