摘要
对山西某炼焦煤选煤厂中煤产品进行磨矿解离,考察了不同磨矿时间下煤样的细度,并对不同细粒级含量的中煤样进行了分步释放浮选试验,结果表明,磨矿解离后能有效分选出中煤中的可燃体成分,全厂总精煤产率可提高6.98%。
Middling product from some Shanxi cocking coal preparation plant was ground for liberation; under different grinding time the fineness of ground product investigated and step release flotation test taken,combustibles be efficiently separated, concentrate yield of the plant be increased 6. 98%.
