摘　　要：介绍了新型充气旋流微泡浮选柱的基本结构和分选原理,指出了新型充气旋流微泡浮选柱的优点。利用充气旋流微泡浮选柱与普通浮选柱进行了对比分析试验,结果表明,在相同的参数条件下,新型充气旋流微泡浮选柱的精煤产率提高了0.57个百分点,尾煤灰分升高了5.03%,有效避免了粗颗粒的跑粗现象,提高了浮选效果,为现场应用及后续设计提供参考。The overall structure and the separation principle of new-type inflatable cyclonic micro-bubble flotation column were introduced, and its advantages were pointed out. Contrast tests between the new-type inflatable cyclonic micro-bubble flotation column and the common flotation column were conducted. The results showed： at the same operation parameters, the yield of clean coal enhanced by 0.57 percentage points and the ash content of flotation tailings increased by 5.03% through applying the new-type inflatable cyclonic micro-bubble flotation column. Thus the escape of coarse particles was avoided, and flotation effects improved. The test results offered reference for field application and subsequent design.
