随着采煤机械化程度不断提高,我国洗煤厂人选原煤中<0.55级细粒煤的含量也逐年增多,给煤泥水处理及煤泥脱水回收增加了难度,而煤泥水处理及煤泥脱水回收是选煤厂生产的重要环节,是降低洗水浓度,实现洗水闭路循环的关键,它不仅关系到选煤厂的正常生
With the continuous improvement of mechanization of coal mining, the content of <0.55 fine coal in raw coal selected by coal preparation plant in our country also increases year by year, which makes it more difficult for slime water treatment and slime dehydration and recovery, while slime water treatment and slime dehydration recovery are Coal preparation plant an important part of production, is to reduce the concentration of washing water, the key to achieve closed loop washing, it is not only related to the normal life of the coal preparation plant
