Simulation Research About the Influence of Particle Characteristics on Transition of Particles in the Horizontal Screw Conveyor

Abstract

Particle products widely exist in the packaging field, such as capsules and nut foods etc. In the practical packaging process, particle products are often needed to be transmitted in the horizontal screw conveyor. Based on the discrete element method, the particle transportation state in horizontal screw conveyor is simulated with EDEM simulator which is extensively used to simulate the movement of particles. The simulation results show that the characteristics of particle itself, such as size, density and the surface rolling friction coefficient, can affect the transition of the particles in the horizontal screw conveyor. Firstly, the average velocity of the particles decreases greatly with the increasing of particle size. Secondly, the average velocity of the particles increases when the particle density increases. Thirdly, the average velocity of the particles decreases with increasing of the surface rolling friction coefficient.
