Abstract：To explore the layering behavior of material particles when swinging vibration,the method of three-dimensional discrete element wsa used to simulation the layering process of plastic balls and steel balls under single pendulum on light groove,combined swing on light groove and combined swing on adding embossment groove.The particle segregation effect was evaluated with the particle volume concentration as the evaluation criterion.The results indicate that the layered effect of combined swing vibration is better than that of single swing vibration,the layered effect of adding convex groove is better than that of the light groove.And volume concentration of plastic ball particles for the adding convex groove can be improved to 10％～15％.
