摘　　要：为了提高振动筛的筛分效率,以倾斜式直线筛为研究对象,以颗粒的形状、投放速率为研究目标,分别对颗粒在筛网上的质量、平均速度及颗粒在筛分过程中的动能变化情况进行分析,研究其与直线筛筛分效率之间的关系。In order to improve the sieving efficiency of vibrating sieve,the inclined linear sieve was taken as the research object,and the shape and delivery rate of particles were taken as the research objective.The mass,average velocity and kinetic energy change of particles on sieve were analyzed respectively,and the relationship between them and the sieving efficiency of linear sieve was studied.
