Particle Behavior Investigation for Different Structures of Hoppers

Abstract

In this paper, two different kinds of hoppers were proposed. In order to investigate particle behavior in hoppers, the discrete element method (DEM) was introduced and soybeans were chosen as test material Particle behavior of four different samples were simulated under different flow rate. Results reveal that the deflection cone greatly affected the particle behavior. After adding the deflection cone in the hopper, the trajectory of particle material can be restrained and the dust diffusion can be reduced.different distances of the deflection cone showed different guiding effect on the particle movement.
