Modeling and Simulation of Horizontal Single Head Screw Conveyor with Different Fill Levels and Rotational Speed Based on EDEM

Abstract

Horizontal-screw conveyor is a key equipment for bulk delivery. In order to optimize the design and improve the efficiency of bulk delivery, this paper makes a depth research on it. Analysis tool (EDEM) with discrete element and a setting periodic boundary model are applied in this work to simulate the horizontal single head screw conveyors grain (e.g. rice) delivery condition under different fill levels and screw rotational speeds. From the analysis of the simulation results, a conclusion can be drawn that when conveying grain materials, horizontal single head screw conveyor should set an appropriate fill level and screw rotational speed according to the property of grain materials, to make the horizontal screw conveyor with a high transmission efficiency and low energy consumption.
