基于粗煤泥分选是选煤厂经营的重点及难点，对选煤厂粗煤泥分选的可行途径进行相应的分析研究。研究表明：螺旋分选机和干扰床是选煤厂分选粗煤泥的可行方法，螺旋分选机适用于粗煤泥的高密度分选，低密度分选适宜采用干扰床分选机，但普通干扰床的分选精度普遍较低，适用于易选或中等可选粗煤泥；带内构件干扰床的应用是今后粗煤泥分选的重要研究方向之一。
基于粗煤泥分選是選煤廠經營的重點及難點，對選煤廠粗煤泥分選的可行途徑進行相應的分析研究。研究錶明：螺鏇分選機和榦擾床是選煤廠分選粗煤泥的可行方法，螺鏇分選機適用于粗煤泥的高密度分選，低密度分選適宜採用榦擾床分選機，但普通榦擾床的分選精度普遍較低，適用于易選或中等可選粗煤泥；帶內構件榦擾床的應用是今後粗煤泥分選的重要研究方嚮之一。

Because that the separation of coarse slime was the emphasis and difficult points in the management of coal preparation plant, the feasible way of the separation of coarse slime in coal preparation plant was analyzed.The research shows, Spiral separator and interference bed are the feasible methods for separation of coarse slime in coal preparation plant, spiral separator is suitable for high density separation of coarse slime, low density separation is suitable for the use of interference bed separator, but the sorting accuracy of conventional interference bed is generally low, and it is suitable for washability or optional medium coarse slime.Application of interference bed with internal structures is one of the most important research direction washability in the future of the separation of coarse slime.
