白羊岭选煤厂煤泥浮选系统可行性研究及效益分析

Feasibility study and benefit analysis of slime flotation system in Baiyangling Coal Preparation Plant

通过对白羊岭选煤厂煤泥粒度组成进行分析,结合煤泥浮选性试验研究结果,综合表明,煤泥含量较高,浮选回收率较高,在最佳浮选条件下,浮选精煤回收率为81.74%,生产更多优质煤产品,有较好的市场前景。从生产技术、设备、经济和销售等方面论述了增加煤泥浮选系统的可行性,每年可增加销售收入3187.2万元,经济效益显著。

Based on the analysis of coal slime particle size composition in Baiyangling Coal Preparation Plant,combined with the experimental research results of coal slime floatability,the comprehensive results showed that the content of coal slime was high,and the flotation recovery rate was high.Under the optimal flotation conditions,the recovery rate of flotation clean coal was 81.74%,and it has a good market prospect to produce more high-quality coal products.The feasibility of increasing slime flotation system was discussed from the aspects of production technology,equipment,economy and sales.The annual sales revenue can be increased by 31.872 million yuan and the economic benefit was remarkable.
