摘　　要： 采用扫描电镜对球磨高炉矿渣粉体和立磨高炉矿渣粉体的颗粒形貌进行了观察.以颗粒投影轮廓的长短径比作为表征颗粒形貌的方法,对2种矿渣粉体的颗粒貌形进行了测量并加以统计分析.结果表明:高炉矿渣粉体颗粒的球形度随着粒径的减小而变差,立磨高炉矿渣粉体颗粒的球形度低于球磨高炉矿渣粉体,二者之间的粒形差异主要体现在0～3 μm粒级. Granule morphology of granulated blast furnace slag powders prepared with vertical mill （GBFS-V） and close circuit ball mill （GBFS-B） respectively were observed with SEM. The ratio of length to breadth （aspect ratio L/B） of the projection figure of the particle was measured statistically. The result shows that sphericity of slag particle decreases with the decrease of parti- cle diameter. The particle sphericity of GBFS-V is lower than that of GBFS-B. The difference between GBFS-B and GBFS-V in particle shape mainly appears in the particles of 0 ～3μm grain grade.
