| 摘 要： | 研究研制了具有稳流斜板结构的新型干扰床分选机,筹建了新型干扰床分选系统,并通过大量试验探索了不同操作参数和稳流板结构参数对分选效果的影响规律,结果发现：对于入料粒度2.8～0.3 mm煤样,在上升水流速36.78、45.25、53.27 mm/s时,随着稳流斜板通道宽度由88mm减小至42 mm,再减小至19 mm,新型干扰床分选机的可能偏差分别减少了0.022、0.064、0.125 g/cm3,从而证明了加入稳流斜板有助于提高干扰床分选机的分选效果。

| Abstract: | A new teetered bed separator with constant flow inclined broad structure was research and developed and a new teetered bed separator system was established.Great experiments were applied to discover the influence law of the different operation parameters and the constant flow broad structure parameters to the separation effect.The results showed that as the coal samples with the feeding particle of 2.8~0.3 mm,when the rising water velocity was 36.78,45.25 and 53.27 mm/s individually,with the channel width o... |
