Research on Structure Optimization of Plow Discharger of Belt Conveyor Based on DEM

Abstract

The belt conveyor is important equipment in the coal mine conveying system. During the conveying process, the plow discharger has problems such as spreading, clogging, and dust pollution. Aiming at these problems, a curved plow discharger head structure is proposed. Through EDEM simulation, the influence of different structural parameters on unloading efficiency is analyzed. The orthogonal test method is used to determine the effect of each parameter, and the optimal parameter combination model is obtained. The research results show that: changing the structural parameters of the plowshare can directly affect the unloading efficiency; the optimized structure of the plow discharger can effectively improve the problems of spreading, clogging, and dust pollution.
