摘　　要：针对张家口洗煤厂原煤中粉煤含量增加,粗煤泥的分选效果变差影响精煤指标的情况,为降低粗精煤灰分,提高精煤回收率,采用CSS粗煤泥分选机替代螺旋分选机,对其进行工艺改造。介绍了粗煤泥系统技术改造的思路、方案和具体实施过程,对比分选效果,结合生产实际,认为选用CSS粗煤泥分选系统进行技术改造非常成功。With the development of mining technology, the content of fines in raw coal increases, which affects the separation effect of coarse slim and the quality of comprehensive clean coal. To reduce the ash of coarse slime and improve clean coal recovery rate, technology transformation is carried out using CSS separator to replace spiral separator. The thought,scheme and implementation process of transformation are introduced. The separation effect in production practice shows that,the application effect of CSS separator in coarse slime separation system is favorable.
