Modelling Studies on a 100 mm Water-Injection Cyclone

Test work on a 100 mm water-injection cyclone was carried out using a ground lead-zinc ore. Experiments were conducted varying the vortex finder diameter, spigot diameter, feed inlet pressure and injection water rate. The effect of variables on the performance of the water-injection cyclone in terms of slurry throughput and corrected cut-size are presented. A set of equations have been developed for predicting the performance of a water-injection cyclone. Further, the reduced efficiency curve was quantified to predict the size distribution of water-injection cyclone products.
