Abstract: Based on the multi-domain fractal theory, the distribution characteristics of each granularity level of coal particles during hydrophobic flocculation were analyzed. The fractal dimension of fine-grained increased from 1.07 to 1.33, indicating that the particle size distribution range was wide, and the internal difference was significant. The fractal dimension of middle-grained decreased from 2.71 to 2.03, showing that the particle size growth noticeable and the morphology of flocs tended to be regular. The fractal dimension of the coarse-grained changes slightly around 2.90, demonstrating that the flocs had a relatively stable spatial structure under the dynamic balance of fragmentation and reaggregation. By introducing the fractal dimension of each granularity level into the flocculation kinetic equation, the conservation relationship between the median particle size and the standard deviation of the floc was quantified, and the analysis of the particle distribution characteristics of the hydrophobic flocculation system at any time was realized.
