Hydrocyclones for Separation Of Solids
At the bottom of hydrocyclone a restrictive "underflow" nozzle allows a portion of the flow, containing the heaviest concentration of solid contaminants to exit the hydrocyclone. The remaining flow reverses direction and exits the top of the hydrocyclone via the "overflow" connection. Hydrocyclones have a fixed flow capacity.
