摘　　要：振动筛是工程中最常用的筛分机械,如何提高振动筛的筛分性能是设计及应用振动筛中面临的重要问题。应用离散元(DEM)法模拟和分析筛分过程,研究了不同的筛分参数对筛分效率的影响,得到了最佳筛分效率下各个筛分参数的值,分别建立振动筛参数与筛分效率关系曲线图。相对于传统方法而言,离散元法在研究筛分问题上具有很大的优越性。Vibrating screen is the most commonly used sieving machinery, how to improve its sieving performance is a major issue during the design and application. Discrete element method （DEM） was employed here to analyze and simulate the sieving process, and the influence of the various sieving parameters on sieving efficiency were studied. In addition, the value of each sieving parameter was derived under optimal sieving efficiency, and the curve of relationship between the sieving parameters and sieving efficiency was established. Contrasted with traditional methods, DEM has great superiority on the sieving study.
