为了解决低阶煤可浮性差的问题,采用新型复配药剂FO1、FO_2、FO3及柴油作为捕收剂,分别在浮选机和浮选柱上进行对比试验,简要分析了浮选柱深度降灰的机理。结果表明,新型高效FO系列药剂可以显著降低药耗量,精煤产率较高;旋流-静态微泡浮选柱作为分选设备较浮选机可以获得低灰精煤,其在煤泥深度脱灰方面有着很大的优势。
In order to solve the problem of poor flotability of low-rank coal, the new compounding agents FO1, FO_2, FO3 and diesel were used as collector to conduct comparative experiments on flotation machine and flotation column respectively. The mechanism. The results showed that the new type of high efficient FO series agents can significantly reduce drug consumption and high yield of refined coal. Swirling-static microbubble flotation column can be used as separation equipment to obtain low-ash coal, Deep deliming has a great advantage.
