粒度特性方程式是用数学方法,处理碎矿和磨矿产物的粒度分析资料,得出的描述粒度分布规律的数学表达式。它不但概括了繁琐的粒度分析数据,而且能把粒度分析资料直接和其他物理量相联系,以便探索碎矿和磨矿过程的规律,指导生产实践。半个世纪以来,国内外很多学者在这方面作了大量的研究,找到了许多种粒度特性方程式,并成功地用它们解决了碎矿和磨矿作业中
The particle size characteristic equation is a mathematical expression describing the law of particle size distribution obtained by mathematical analysis of the particle size analysis data of the crushed ore and the ground product. It not only summarizes tedious granularity analysis data, but also correlates the particle size analysis data directly with other physical quantities in order to explore the law of the crushing and grinding process and guide the production practice. For half a century, many scholars at home and abroad have done a lot of research in this area, found many kinds of grain size characteristic equations, and successfully used them to solve the crushing and grinding operations
