MODELLING THE STICKIES DISPERSING MECHANISM IN DISK DISPERSERS

Based on the theory of two-phase flow, the disk thermal dispering mechanism and influence to stickies was analyzed in this paper. The force between fibers and stickies was focused on when the disk was working. The results showed that stickies were peeled from fibers and dispersed into small particles during the flowing procedure of the pulp, which can be contributed to the force applied on liquid phase by the solid phase and the acceleration force produced by the flowing solid phase.
