Abstract:

The impact of different particle sizes,speed and rotator position to the flow line of tar cutting pump and solid particle distribution are analyzed in this paper.The result of the numerical simulation shows that low flow would cause serious vortex flow and little impact to the solid-phase concentration distribution and that the bigger the particle sizes and concentration,the higher the concentration of solid-phase of the rotator working medium,and the more serious wearing and erosion to the rotator surface.It also suggests that the increased speed may improve pulverizing efficiency and may undermine the life expectancy of the equipment.
