Discrete element modeling (DEM) is the most suitable modeling technique to simulate the mass flow of particles in chamber recently, which is an important part of VSI to break rock. DEM is presented in this message to predict sand production within a US7 vertical shaft impact crusher. Sand production is one of important parameters to judge the productiveness of VSI.

Breakage is an essential process in many industries notably for mineral processing. this mode of particle fracture is likely to be of significance for a number of crushers as well. This has led to an increased demand in the simulation of particle breakage and degradation to better describe fracture of particles subjected to repeated loading.
