摘　　要：针对禾草沟煤业选煤厂TBS溢流采用振动弧形筛脱水脱泥效果差、底流灰分偏低问题,从最高精煤产率原则出发,采用电磁筛改善TBS溢流精矿脱泥,采用螺旋分选机对TBS尾矿进行再选。改造实施后,改善了粗煤泥分选、脱泥效果,精煤产率提高1.196%,中煤产率提高0.225%,经济效益显著。In view of the poor dewatering effectof vibrating curved screen and low ash content of the bottom flow of the TBS overflow in Hecaogou coal preparation plant,an electromagnetic screen was used to improve the demudging of the TBS overflow concentrate and a spiral separator was used to sweep the TBS tailings from the principle of the highest clean coal yield.After the implementation of the transformation,the sorting and desliming effect of coarse coal slime has been improved,the yield of clean coal has increased by 1.196%,the yield of middling coal has increased by 0.225%,and the economic benefits are remarkable.
