灵山选煤厂采用双系统生产流程,一部分洗红阳煤,生产精煤供鞍钢作炼焦用煤,另一部分洗阳泉矿无烟煤,供鞍钢用于高炉喷吹。喷吹用的精煤要求水分越低越好。为了降低综合精煤全水分,几年来,该厂曾采用重选、浮选和筛选相结合的流程。精煤水分虽有所降低,但对精煤水分起主要作用的浮选精煤的水分仍高达26～28%,始终没有找到降低水分的办 Lingshan Coal Preparation Plant using dual-system production processes, part of the wash Hongyang coal, coal for the production of coke for the Anshan Iron and the other part of Yangquan Mine anthracite for Angang for blast furnace injection. Fine coal used to spray water as low as possible. In order to reduce the overall moisture content of integrated coal, the plant has adopted the process of re-election, flotation and screening in the past few years. Although the coal water has been reduced, but the main function of the water from the flotation of clean coal water is still up to 26 ~ 28%, and did not always find ways to reduce the water
