EFFECT OF ANGLE OF HYDROCYCLONE INCLINATION ON CUT SIZE
The influence of angle of hydrocyclone inclination on its cut size was studied in a specially designed laboratory rig equipped with a 75 mm Krebs cyclone. It was found that by increasing the angle of inclination of the cyclone, the cut size increases in particular for angles above 45°. For the low p...

Summary: | The influence of angle of hydrocyclone inclination on its cut size was studied in a specially designed laboratory rig equipped with a 75 mm Krebs cyclone. It was found that by increasing the angle of inclination of the cyclone, the cut size increases in particular for angles above 45°. For the low per cent solids (10%), the effect of inclination was not significant. The relative increase in the cut size for the angle of 90° and a per cent solid of 30% was found to be 24.5%. An increase of 10% in the per cent solids increased the cut size by 31%. Based on 38 experiments, an empirical model similar to the one proposed by Asmoah and Napier-Munn to predict the cut size was tested.
On a étudié l'influence de l'angle d'inclinaison de l'hydrocyclone sur sa fraction granulométrique dans un appareil de laboratoire spécialement conçu et équipé d'un cyclone de Krebs de 75 mm. On a trouvé qu'en augmentant l'angle d'inclinaison du cyclone, la fraction granulométrique augmentait, plus particulièrement pour les angles au-dessus de 45°. Avec un faible pourcentage de solides (10%), l'effet de l'inclinaison n'était pas important. On a trouvé que l'augmentation relative de la fraction granulométrique était de 24.5% avec un angle de 90° et un pourcentage de solides de 30%. Une augmentation de 10% du pourcentage de solides augmentait la fraction granulométrique par 31%. Basé sur 38 expériences, on a évalué un modèle empirique similaire au modèle proposé par Asmoah et Napier- Munn pour prédire la fraction granulométriques. |
