摘　　要：基于弹性筛面潮湿细粒物料筛分理论 ,研究了梯流筛筛面动态特性 ,提出了梯流筛筛条设计公式 ,认为梯流筛能较好地完成难筛分物料的筛分任务 ,是其筛面弹性振动大 。On the basis of elastic surface theory of mosit fine materials,the dynamic characters of casade screen surface are studied.The design formula of screen bar is driven.According to the analysis,the conclusion that the cascade has high rate of aperture,and the screen surface has a large elastic vibration amplitude are drawn.

关 键 词：梯流筛 筛分机理 弹性振动
