以山东鱼台地区选煤厂细粒煤泥为研究对象,分析了该煤泥的煤质特性。在药剂用量试验和浮选浓度试验的基础上,利用浮选机作分选设备,最终得到精煤产率为56.55%,精煤灰分为8.78%的浮选指标;利用浮选柱进行了试验探索,得到精煤产率为57.87%,精煤灰分为8.71%的浮选指标,表明浮选柱是处理细粒煤泥浮选降灰提质的有效设备,浮选指标好,经济效益显著。
Taking the fine coal slime in Yutai coal preparation plant of Shandong Province as the research object, the coal quality characteristics of the slime are analyzed. Based on the experiment of reagent dosage and the flotation concentration test, the flotation machine was used as the sorting equipment to get the flotation index of 56.55% of the refined coal and 8.78% of the coal ash, and the flotation column was used to test Exploration, get 57.87% of coal yield, fine coal ash is divided into 8.71% of the flotation index, indicating that the flotation column is the treatment of fine coal flotation ash quality upgrading of effective equipment, flotation indicators, significant economic benefits.
