摘要：针对立磨和实验室球磨机粉磨的粉煤灰中球状玻璃体的破坏程度进行研究，并对其与粉煤灰活性的相关性进行分析。结果表明，球形颗粒破坏度更高的粉煤灰在粉磨后可表现出更高的活性，球形颗粒破坏度应作为评价粉煤灰粉磨效果的一项重要指标。

Abstract：In this article，the failure degree of spherical glass body in the ground fly ash produced in vertical mill and ball mill in the lab is analyzed. The relationship between it and the fly ash activity was analyzed. The results show that, when more spherical particles are destroyed，fly ash shows higher activity. Therefore, the spherical particle size destruction degree should be treated as an important indicator to evaluate the grinding effect.

Key words：fly ash，grinding，spherical particles destruction，activity
