磨机钢球直径的选择历来主要是凭经验,考虑的因素不全面,故误差常常很大.段希祥从破碎力学原理出发推导出理论性较强的球径计算半理论公式.该公式在实际应用中表明,对于中磨及细磨极为准确,但对于粗磨,误差还是偏大,尽管仍比传统的方法准确.为此我们从岩矿的力学性质开始研究该公式的修正,通过试验室试验及工业试验,得到了不仅能准确计算中磨、细磨,而且能准确计算粗磨球径的方法.

In the past, the determination of mill ball size was mainly conducted by experts experience and generally involved great deviation because not all factors were properly considered. Professor Duan Xixiang…has developed a half-theory formula from principle of fragmentation mechanics. In practice, it has been proven that the formula can be satisfactorily applied to intermediate and fine grinding stages. However, it still results in obvious deviation to the large side although it is better than any other methods. In view of this, starting from rocks mechanical properties, we take pains to study the revision of the formula. After carried out a series of lab test and industrial experiments, we develop a scientific and reliable system of accurately determining mill ball size for coarse grinding as well as intermediate and fine grinding processes.
