| 摘 要： | 钴结壳破碎块度是衡量螺旋滚筒式采矿头破碎效果的重要指标，也是集矿和扬矿系统的设计依据．对常用的4种矿岩破碎粒度分布公式进行了分析，利用线性回归按4种分布公式对实验数据进行拟合，得出分形分布能更准确地描述钴结壳破碎块度分布特征，分维数能定量描述富钴结壳破碎的块度组成，图2，表2，参10．

| Abstract: | The granularity of cobalt - rich crusts is an important index to evaluate the crushing effect broken by spiral - cutting head, it is also the design gist of collecting and lifting system. Four type of granularity distribution formula were analyzed in this paper, and according to these formula, the experiment data was fitted by the use of linear regress. In above distribution law, the fractal distribution is able to wse to describe the characteristics of cobalt crust granularity more accuracy. The fractal dimension can quantitatively express the broken cobalt crust contents of different size. 2figs. , 2tabs. , 10refs. |
