| Abstract: | The characteristics of flowing fluid (water)in the initial region of spiralsluice, such as the thickness of fluid film, average velocity, Reynolds number,unit width rate of flow, accumulated rate of flow and net rate of radial flow etc,are studied in this paper. Through analyses and demonstrations, the conclusionis reached that the flowing fluid in the initial region of spiral sluice transportslight minerals to outer edge mainly, which is favourable to the separation oflight minerals from heavy ones. |
