Abstract:An experimental study on the flow pattern within a 60 mm × 600 mm transparent air-sparged hydrocyclone was carried out , from which it was firstly found that the liquid column at the bot-tom of the cyclone is one of the essential characteristics in the air-sparged hydrocyclone, and a further study was done to investigate the effect of the liquid column height on the cyclone performance. The bubble velocity in the liquid column was measured using a pickup camera. The tangential and axial velocities in the swirl-flow layer were also examined. The results are conduciveto the further application study of the air-sparged hydrocyclone.
Key words: air-sparged hydrocyclone flow field froth flotation centrifuge process
