摘要
利用分形和分维数基本概念,导出破碎粒度分布的分维数和分裂比、粉碎概率互相存在的简单关系,从能耗与表面积相关出发,推出单位体积破碎能耗与粒度分布的分维数的相关性;当破碎粒度分布的分维数小于1,破碎能耗呈现自然分形的特征.
The simple relationship between fractal dimensions of comminuted particle distribution the reduction ration and the probability of fragmentation is derived from the fundamental concepts of fractal and fractal dimension.Starting from the relationship between the energy consumption and the surface area,the relationship between the energy consumption and the comminution particle distribution fractal is obtained.When the fractal dimensions of comminuted particle distribution is smaller than one,the consumption of energy presents the feature of nature fractal.
