摘要： 云煤能源安宁分公司配合煤细度存在合格率低和细度波动大的问题，应用小焦炉试验研究了单种煤和
配合煤细度与CSR 的关系；通过调整3 # 粉碎机变频器频率至3 9 Hz，提高了配合煤细度合格率；对于6 m 顶装
焦炉，当配合煤细度越接近7 6 % 时，焦炭CSR 越处于较好水平。

Abstract: Anning branch of Yunnan Coal and Energy Co.，Ltd. faces problems of low quality rate and
great fluctuation of blending coal fineness. Pilot oven test is conducted to study the co-relations between
fineness of individual coal and blended coal and CSR. Fineness of blended coal is improved by adjusting
the VFD of No.3 crusher to 39 Hz. For 6m top charging battery, the closer the blended coal fineness is to
76%，the better the CSR will be.
