中文摘要：

采用DEM理论,分析垂直螺旋输送机中散料的受力和位移的关系,并导入垂直螺旋输送机模型,采用EDEM软件,分析垂直螺旋输送机内散料在不同条件下的运动情况,得出影响散料运动的因素,对于提高垂直螺旋输送机的生产率具有一定的意义。

英文摘要：

The DEM theory is adopted for analysis of correspondence between load-carrying of bulk materials and dis-placement in vertical screw conveyor , with the model of vertical screw conveyor imported to analyze movement of bulk ma -terials under different conditions by EDEM software , to figure out some factors affecting movement of bulk material , which will provide certain guidance for improving production rate of the vertical spiral conveyor.
