摘　　要：针对西曲选煤厂浮选尾煤灰分偏低的问题,通过对尾煤进行筛分及浮沉试验,分析了其中的原因。通过对分级旋流器分级效果影响因素的分析以及粗煤泥分选回收工艺流程的优化,提出了通过调整分级旋流器结构和操作参数以及优化粗细煤泥分级、分选工艺流程,来合理调整粗、细煤泥进入粗煤泥分选系统和浮选系统的比例,降低浮选入料的粒度上限,提高浮选尾煤的灰分。Based on coal flotation tail low ash content in Xiqu Coal Preparation Plant, the tail coal screening and fugitive dust experiment was carried out, the reason was analyzed. Through the analysis of the factors of classifying hydrocyclone classifier and coarse coal slime separation recycling process of optimization, adjusting the optimization of structural and operating parameters and grading hydrocyclone thick coal slime grading and separation process were put forward, which reasonably adjusted the coarse and fine coal slurry into the proportion of coarse coal slime separation and flotation system,reduced flotation into the material particle size limit and improved the flotation of coal ash.
