Optimal Research for Ball Mill Medium Test in Sizhou Concentrator

介绍了在实验室中进行球磨介质研究与优化的方法。以精确化装补球理论基础为依据,根据所选矿石的力学性质,精确地计算出初装球的球径和球比,最终确定了70∶50∶40∶30=20∶30∶20∶30的磨机初装球比方案。该方案与现厂方案相比,磨矿产品细度显著提高,而且产品粒度组成趋于合理,进而提高了浮选过程指标。

This paper introduced a research and optimization method for ball mill medium in laboratory. Frist, the ac- curate loading and addition of milling balls theory were taken as the basis, based on the mechanics feature of the ore, we can compute the initial installation ball diameter and proportion of the ball accurately and eventually get the Ф70 ： Ф50 ： Ф40：Ф30：20 ： 30 ： 20：30. Compared with the factory plan, the grinding product fineness obviously increases and the size distribution becomes reasonable, which improves the flotation indicators.
