摘要
分析了气固流化床（即空气重介质流化床）的形成过程及其分选原理，通过理论推导，给出了气因流化床密度的计算公式，实验结果表明：该计算公式精度较高，可用于分选密度的预测。
In this paper, on the basis of analysing Of formation and separation mechanism of gas-solids fiuidised bed, the calculation model of density of fluidized bed is proposed theoretically. The experimental resultsshow that the model can be used to calculate the separation density with high precision.
