摘要
由于捞坑分级效果差,导致+0.5mm超粒进入浮选系统,对浮选各工艺环节产生很大的影响,经过粗煤泥回收系统的改进,使大部分粗精煤得到回收,显著地提高了经济效益。
Because the pit graduation effect is bad, causes ＋0. 5 rnrn ultra grain into the flotation process system, and produces very tremendous influence to the various link of flotation process. With the thick coal sludge recovery system＇s improvement, makes the majority of thick refined coal obtain the recycling, obviously raises the economic efficiency.
