摘　　要：针对吕家坨矿选煤厂入选原煤煤质变化较大、浮选入料粒度细及灰分偏高导致浮选精煤回收率低等状况,采取了加强制度管理、改善过滤机滤饼脱落效果、选用新型药剂等措施,使精煤产率有所提高。According to the status about lower flotation productivity of washed coal with larger vary of coal quality and higher ash, some measures were taken, such as strengthening system management, improving deciduous effect of filtering machine and selected new-style medicament, so as to improve productivity of washed coal.
