摘　　要：梗阳选煤厂采用煤泥二次浮选、精煤泥两段回收工艺流程,潘一选煤厂采用煤泥全部精选工艺流程,结合生产检查数据,对>0.045 mm和<0.045 mm两个粒级的分选效果进行分析。数据分析表明:前者适用于<0.045 mm粒级灰分较低的浮选物料分选,后者仅适用于高灰细泥产率高的浮选物料分选。While two- stage flotation process for coal slime two- stage recovery technology for clean coal slime is used in Gengyang coal preparation,cleaning process for all coal slime is employed in Panyi coal preparation. According to production data,comparing separation effect between plus 0. 045 mm slime and minus 0. 045 mm materials,the former technology is appropriate for the minus 0. 045 mm materials,and the latter is only applied to high- ash fine slime.
