| 摘 要： | 东曲矿选煤厂因入浮煤泥可浮性差、浮选设备能力不足,使浮选作业效率低;通过增设表面改质机,并用两台微泡浮选机替换了两台旧的浮选机,明显改善了分选效果;在浮选精煤灰分变化较小的情况下,浮选精煤产率提高约8%~10%,总精煤产率提高约1.6%~2.0%,取得了可观的经济效益。

| Abstract: | The efficiency of coal flotation at Dongqu Coal Preparation Plant was low due to inferior floatability of coal slime and insufficient flotation facility.Remarkable improvement achieved by addition of a coal surface property modifier and replacement of two old flotation machines with two micro-bubble ones that:under small variation of concentrate ash,flotation concentrate yield increased 8～10%,leading to increase of overall clean coal yield at 1.6～2.0% and considerable economic benefit obtained. |
