DEM Simulation of Spin Vibration Screening Process

Article Preview

Abstract:

This paper focus on the motion simulation and visualization of the material particles in the operation of the spin vibration screening using DEM(Discrete Element Method). Based on analysis of the simulation results, some conclusions are made which provide the theory basis in order to design the screen parameters reasonably. Finally some experiments are carried out in order to verify the correctness of the simulation.
