Abstract: A mathematical model of the hydrocyclone, based on the physics of fluid flow, has been developed. The model equations are solved in a computer code that takes as input the hydrocyclone dimensions and feed slurry characteristics. The output of the computer code is the velocity profiles of the fluid and the separation efficiency curve. To validate the model, an LDV was used to measure the velocity profiles inside a 75-mm hydrocyclone. Pure water and glycerol-water mixture were used as the working media to simulate the increase of slurry viscosity in the presence of solid particles. The predicted velocity profiles agree well with the experimental measurements. Dilute limestone slurry was also classified with the same hydrocyclone, and predicted the separation efficiency curve shows good agreement with experimental observation.
TL;DR: In this article, a methodology for simulating the performance of hydrocyclone was developed to compare experimental and simulated results generated using different turbulence models in terms of water throughput and split with the help of suitably designed experiments.
TL;DR: In this paper, the effect of mechanical and chemical removals of fine minerals by hydrocyclone and dispersants on coal flotation has been investigated and it was concluded that the best way to increase the flotation recovery in the presence of clays was to remove these fine minerals using mechanical means such as hydrocylones.
