100—5微米的细泥重选在工业上已取得了显著的进展,但理论研究却相形见拙。近年来不少重选工作者引用了拜格诺力的概念,运用拜格诺的理论来解释床层松散问题。众所周知,床层松散适度是物料按比重分层的前提。本文较系统地介绍了拜格诺的有关理论、拜格诺力的计算方法及其在重选设备中的应用,并提出了若干应进一步研究的课题。 The fine sediment re-election of 100-5 microns has made remarkable progress in industry, but the theoretical research is quite clumsy. In recent years, many reelection workers quoted the concept of Bayonot power, using Bayneau’s theory to explain the problem of loose beds. As we all know, the appropriate loose bed is the premise of the material according to the proportion of stratification. This article systematically introduces Bayesian theory, Bayesian Forces calculation method and its application in re-election equipment, and put forward a number of issues to be further studied.
