發(fā)布時間:2018-12-11 16:37
【摘要】:以臨渙選煤廠難浮煤泥為研究對象,先后進行浮選入料的粒度分析、密度分析,現(xiàn)場精煤的粒度分析,結(jié)果表明高灰細泥污染是影響精煤質(zhì)量的主要因素。接著進行煤樣的分步釋放試驗、現(xiàn)場尾礦的掃選試驗、煤樣的精選試驗,結(jié)果表明:通過精選,減輕了高灰細泥對精煤的污染,并提高了粗顆粒精煤的回收。
[Abstract]:Taking the difficult floating slime in Linhuan Coal preparation Plant as the research object, the particle size analysis, density analysis and field fine coal size analysis of floatation feed are carried out successively. The results show that the pollution of high ash and fine mud is the main factor affecting the quality of clean coal. Then the step release test of coal sample, the cleaning test of tailings and the cleaning test of coal sample are carried out. The results show that the pollution of high ash and fine mud to the clean coal is reduced, and the recovery of coarse fine coal is improved.
