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 percent solids (10%) the effect of inclination was not significant. The relative increase in the cut-size for the angle of 90° and percent solids of 30% was found to be 24.5%. An increase of 10% in the percent solids increased the cut-size by 31%. Based on 38 experiments an empirical model to predict the cut-size was proposed.
