Jaw Crusher Simulation Rocky DEM Discrete Element Method

Apr 04, 2019 Rocky DEM simulates the particle breakage in Jaw Crusher equipment. It is possible to prescribe the complex motion of the Jaw due to the robustness and flexibility of motion kernel technology developed by Rocky DEM. The wear model implemented in the solver predicts the abrasive wear of solid surfaces due to the action of impacting particles.
