Abstract
The sedimentation in the field of gravity provides a practicable and scientific principle for solid-liquid separation of ultra-fine particles. According to the fractal theory, a model of ultra-fine particles for gravity sedimentation was developed, considering the aggregation effects and particles interference, and the aggregation promoting coefficient was put forward. The fractal structure and FSD of aggregates were also analyzed. Furthermore, the comparison between theoretical and experimental values of ultra-fine particles sedimentation showed that the two results were more consistent with each other for the suspension concentration ranging from 1 wt% to 5 wt%.
