Hydrocyclone Design Student Cheresources.com Community

I am currently doing my final year design project which involves the design of a hydrocyclone for separation of solids from slurry. The total flow is about 5000 L/min, and the density difference is about 0.6g/cubic cm. Based on the Bradley Design equations, I got a diameter of about 55 cm, and a pressure drop of about 65 psi.

Hydrocyclone Feed Pump & Pressure PSI vs Operating Parameters

The problem now is to control the efficiency of the hydrocyclone. To do this you control the density of the cyclone. To do this you control the density of the cyclone. Because the cyclone works upon the pressure inside of it, adding or taking away water that is being fed to it will control the grind of the ore being discharged.

Solids Capture The University of Arizona

Total suspended solids (TSS) concentration is defined as the mass of particles above 1 µm in diameter (APHA, 1989) occurring in a known volume of water. Suspended solids have both inorganic and organic components. The organic portion, known as volatile suspended solids (VSS), contributes to oxygen consumption and biofouling problems.
