阻尼液固流化床分选粗煤泥的试验研究

The experimental study on damping fluid bed separation to coarse slime

通过对3．00～0．25mm粒度级别粗煤泥，在实验室采用无阻尼柱形及有阻尼矩形2种液固流化床（即干扰床）进行对比分选实验，分选实验结果表明：在液固流化床中添加阻尼块后，分选效果得到了提高，笔者分析了其原因，并通过实验提出了下一步阻尼液固流化床的研究方向。

The coarse slime that size is 3.00mm to 0.25mm has been respectively separated by columned fluid bed without damping and rectangle fluid bed （TBS） with damping at laboratory. The result indicates that the effection can be improved if the fluid bed holds damping blocks. The reason is analysed in this paper, and the following research direction of damping fluid bed is clear through this experiment.
