涡北矿原煤脱泥分选与不脱泥分选工艺的比较
|
摘要
通过对涡北矿原煤采用选前脱泥与不脱泥的分选工艺进行对比,分析其优缺点,并从精煤产率、数量效率、精煤合格率、介耗、油耗、电耗等方面进行了全面的分析和探讨,得出采用不脱泥无压三产品重介旋流器洗选工艺具有工艺简单、设备投资少、精煤产率较高、生产成本较低等优点。
Following a comparison of the two processes for treating respectively dislimed and undislimed raw coal,the paper elaborates on the advantages and disadvantages of each process in terms of clean coal yield,organic efficiency,rate of qualified product,and medium,oil and power consumptions.Based on the result of an in-depth study of all of the factors involved,the process for treating undislimed raw coal using gravity-fed 3-product H.M.cyclone is proposed.Practice shows the use of the system can lead to a higher yield of clean coal at a lower operating cost,and the system is simple in process and low in investment on equipment.
