摘　　要：提高硅灰石粉的长径比是对非金属矿硅灰石进行深加工、改善其附加值的主要技术。以湖北大冶地区的样品为例,探讨了硅灰石加工技术中的统计方法、粒级、长径比分布特点对平均长径比测定的影响。通过实验结果及其分析表明,由于统计方法的不同,同种硅灰石粉体偏光显微镜测定的平均长径比可以相差20%左右;硅灰石平均长径比与硅灰石粉体颗粒的粒级范围有关;把平均长径比的评定和长径比分布特点进行综合分析,更能反映硅灰石的粉碎效果。Changes in the aspect ratio of wollastonite powder are the key technologies for its deep processing and valueadding. Taking Hubei Daye region as an example, different statistical methods, grain size, characteristics of aspect ratio distribution are discussed. Experimental results and analysis show that because of the different statistical methods, the average aspect ratio measured by the same polarizing microscope wollastonite powder can be a difference of about 20 % ; the average aspect ratio wollastonite is related to the wollastonite powder particles tablets; the crushing effect of wollastonite can be reflected by analyzing the average ratio length and aspect ratio diameter assessment and distribution.
