The influence of apex diameter on the pattern of solid/liquid ratio distribution within a hydrocyclone

Knowledge of the pattern of solid/liquid ratio distribution within a hydrocyclone is very important for reliable design and efficient operation. This pattern was examined using a 100mm hydrocyclone for a wide range of apex diameters at high solid contents of the feed pulp. The measurements were taken along orbit radii at several horizontal level positions along the cyclone length. The results give a complete pattern of pulp‐solid content distribution for the studied parameters. An empirical equation relating the pulp solid/liquid ratio with all the studied variables was established. The predicted data show good agreement with the experimental results.
