The models of Rubber Roller Husker Vibrating Feeder and rice particle are obtained through the discrete element analysis software EDEM. Simulate the movement of material flow in the vibrating feeder by setting up the corresponding parameters. The average speed of single particle is 0.22 m/s roughly under the theoretical parameters, and the average velocity of material flow is around 0.24 m/s. The trajectory is achieved and the feeding uniformity is discussed. In order to verify the feasibility of the simulation results, adopt vibration meter GM63B to measure the actual velocity of material flow under the different amplitude in the experimental vibrating feeder, which can provide reference for analysis of material flow in the new vibrating feeder design.
