任家庄选煤厂粗煤泥分选工艺改造

Renovation of coarse slime separation process at Renjiazhuang coal preparation plant

针对任家庄选煤厂原煤煤质变差的问题,提出了解决方案:在重介选煤工艺前增加脱泥筛对原煤预先脱泥,并采用分级旋流器+TBS干扰床分选机联合工艺对脱泥筛筛下粗煤泥进行回收。生产结果表明,该工艺对粗煤泥具有较好的回收效果。

To solve the problem of poor quality of raw coal encountered in Renjiazhuang coal preparation plant,proposed that adding desliming screen at the position before the dense medium process for pre-desliming,and the coarse slime in underflow of the desliming screen was recovered by combined process of cyclone classifier ＋ TBS teetered bed separator,The results of production indicated that this process proved have significant recovery effects to the coarse slime.
