1引言自从有关棒磨机的一篇综述（MclvorandFinch，1986）发表以后，作者在7座不同的选矿厂进行了30多个棒磨效率试验。文献中还有几篇令人感兴趣的有关律磨机的文章。本文介绍综述发表以来所进行的研究中最重要的发现，以及用于评价棒磨机磨矿效率的技术进展。2棒磨机功率输出 1 Introduction Since the publication of a review of rod mills (Mclvorand Finch, 1986), the authors conducted more than 30 rod mill efficiency tests at seven different concentrator plants. There are several interesting articles about the mill in the literature. This article presents the most important findings of the research carried out since the publication of the review, as well as the technical advances used to evaluate the grinding efficiency of rod mills. 2 rod mill power output
