摘　　要：通过潮湿细粒煤炭堵孔机理及其克服堵孔办法的研究 ,提出了弹性筛面的筛分理论 .建立了琴弦筛面、弹性筛面动力学模型及设计公式 .揭示了琴弦筛面、弹性筛面克服堵孔的机理 .得出要提高潮湿细粒煤炭筛分效率 。Screening theory of elestic screen was proposed by studied blinding apertrue machanism of moist fine coal and the way of overcoming blinding. The dynamic models of piano wire screen surface and elastic screen surface were set up, the design formula of screen surface was given. The overcoming blinding mechanism of elastic screen surface was accounted for. Finally, the results showed that it was important to improve amplitude of screen surface so as to improve screen efficiency.
