Effect of Feed Angle on Centrifugal Flotation Cell

Feed angle have a great effect on the flotation efficiency of self-priming centrifugal flotation cell.In order to improve the efficiency of flotation,the effect of feed angle on the flow field in a self-priming centrifugal flotation cell was investigated using STAR CCM+.The distribution law of velocity,pressure,turbulent kinetic energy under different angles was gotten.The turbulent kinetic energy and the pressure difference increased with the feed angle. Result shows that the feed angle acting on the interior flow field is significant and the feed angle of 20º is more conducive to flotation than others.Conclusion can provide a theoretical foundation for improving flotation efficiency and optimizing flotation structure.
