关于选煤厂实现洗水闭路循环的若干问题

Some Aspects of Closed Water circuit of Coal Preparation Plant

煤泥回收和洗水处理是洗煤工艺过程的重要环节,它关系到环境保护、煤炭资源的回收利用和洗煤生产、管理上的一系列问题。特别是环境保护工作的开展,要求选煤厂不外排工业废水,解决对水源和农田的污染。实现洗水闭路循环是选煤厂生产上亟待解决的问题。邢台煤矿选煤厂在生产发展的进程中,

-Much work has been done for achieving closed water circuit in Xingtai Coal Preparation -Plant including: direct floatation of slime, which eliminates accumulation of fines in the water; promoting the effect of floatation in processing the waters reducing the concentration of water and improving the results of separation; changing the features of the feed to thickner; balancing of water and control of fresh water quantity; recovery of tailings from floatation cells in the washery etc.
