摘　　要：为提高新型液固流化床分选粗煤泥的效果,考察了主要参数对新型液固流化床分选的影响规律。结果表明精煤产率和精煤灰分随着上升水流流量增大而增大;精煤产率和精煤灰分随着脉动频率和脉动幅值变大呈现先逐渐增大而后减小的变化趋势。In order to improve the separation efficiency of the new style liquid-solid fluidized bed used for coarse slime beneficiation, the influence of the main parameters on the separation law of the new style liquid-solid fluidized bed were investigated. The results show that the coal yield and ash content of clean coal increase with the increase of the rising water flow. The coal yield and the ash content of clean coal firstly increase, and then decrease gradually with the increase of the pulsating frequency and the pulsating amplitude.
