Equilibrium zone concept is one of the most used approaches for equipment design. This work revisits the design equations for nonspherical particles and compares design results considering nonspherical geometry to results considering spherical geometry and correcting the values to the non-spherical particle geometry.

HYDROCYCLONE SEPARATOR Hardware All hydrocyclones are composed of four (4) main sections: 1. Inlet The inlet section is comprised of a cylindrical feed chamber which serves to convert the incoming flow to a tangential flow with minimal turbulence. Critical design variables include the inlet area and inlet type. Smaller inlet sizes
to as total height of hydrocyclone. And for this project the total height of the hydrocyclone is 0.40m. Cut size: The cut size is defined as the diameter ( ) of a particle, which has a probability of n% to end up in the underflow section. The design probability (n) of trapping of particles in the collection basket was taken as 50%.

In the study, we have tried to calculate the solid-separation efficiency by the commercial CFD model for the design and manufacture of a hydrocyclone. From the results, the following conclusions have been drawn: A helical vortex is the most important factor to describe because it helps to separate solid and liquid from the slurry.

design velocities determined by the different air densities were used for the tests. Experimental results indicate that optimal cyclone design velocities, which are 16 m/s (3200 ft/min) for 1D3D cyclones and 15 m/s (3000 ft/min) for 2D2D cyclones, should be determined based on standard air density. It is important to consider the air density effect
