摘要：运用离散元方法(DEM)分析转运站中的物料流动,设计优化新型带式输送机转运站结构,从源头上控制灰尘产生,实现转运站的无动力或微动力抑尘;针对转运过程中出现的问题,利用EDEM软件对优化结构进行分析。结果表明,无动力抑尘转运站结构适用性强,能有效解决转运过程中的物料速度慢、冲击、堵料、磨损等问题。

Abstract：Based on the structure design of the new belt conveyor, EDEM simulation was used and a comprehensive analysis of a optimize structure was made which aimed at some important problems in the process of transportation. The simulation try to reduce dust generation from the source control,which not only realize transfer station of no power or micro power, but also break the limitation of traditional design and expand the product scope. The results show that the structure of the non-power-drive dust suppression transfer point has strong applicability, which can effectively solve the problems such as particle velocity, compacting, blocking material and wearing.
