A fractal model for the size distribution was proposed based on the fractal character of the crushing granularity of rocks. The crushing tests of three different rocks were conducted. And the test results of rock size distribution were used to conduct a statistical analysis. The results indicate that the fractal characteristics of rock are universal. The fractal dimension is one of perfect indicators to evaluate crushing, reflecting the whole process of the rock crushing. Subsequently, the relationship between fractal dimension and both of size of rock and energy consumption is established. It gives a better explanation from the aspect of mechanism. What’s more, the fractal dimension represents the effect and the rule of the size distribution of crushing and provides a theoretical foundation for controlling the size distribution of rock.
Key words: fractal dimension / size distribution / crushing test / broken indicators
