摘要：In respect to conventional particle size distribution, the fractal size dimension (FSD) has become a powerful tool for characterization of particles. In this paper, we applied both the single fractal law and the bi-fractal approaches to analyze the fractal and mutifractal characteristics of the Qingshuiying coal particles in the ultra-fine pulverizing process. The relationship between FSD and the ultra-fine pulverizing time was detected and had certain guidance meaning for optimizing the operational parameters and reducing energy consumption of the ultra-fine pulverization.
