摘　　要：细粒煤泥进行筛分过程中存在筛分效率低、精煤质量低的问题,针对这一问题,采用弛张筛工艺参数实验分析的形式对筛分过程中的工艺参数进行优化。结果表明,筛分的工艺参数为工作频率9.33 Hz、处理能力为360 t/h时的筛分效果最佳,可以提高11%的筛分效率。There are problems of low screening efficiency and low quality of clean coal in the screening process of fine coal slime.Aiming at this problem,the process parameters in the screening process are optimized in the form of experimental analysis of flip screen process parameters.The results show that the screening effect is the best when the screening process parameter is 9.33 Hz and the processing capacity is 360 t/h,which can improve the screening efficiency by 11%.
