Relation analysis of fly ash spherical particles destruction and activity after grinding.

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. [ABSTRACT FROM AUTHOR]
