摘要
常村煤矿选煤厂自重介生产系统和煤泥浮选系统投运后,浓缩尾煤灰分持续偏低,为有效控制煤泥灰分和提高生产效益,选煤厂采取加压过滤机滤液水闭路回收和捞坑溢流水工艺管道改造措施,高效地解决了浓缩尾煤质量问题,取得了显著的经济效益。
After the production system and coal slime flotation system was put into operation,concentrated tail constantly low ash content,for the effective control of the coal ash content and improve the production efficiency,coal preparation plant to take pressure filtration machine filtrate water closed-circuit overflow water recycling and sludge pit and modification measures,process piping efficiently solve the problem of the enrichment tail coal quality,has obtained the remarkable economic benefits.
