A pump or other external pressure source causes a liquid mixture to flow through the hydroclone.
The mixture enters tangentially and spins in the hydroclone’s shaped entry chamber.
Spinning causes the denser fraction (such as particulate solids) to be centrifugally thrown toward the wall of the chamber, then continue on a downward spiral path along the shaped wall to the outlet at the bottom center. This outlet is known as the underflow.
The less-dense fraction moves in the opposite direction, spiraling upward around the center axis of the hydroclone toward the outlet at the hydroclone’s top center. This outlet is known as the overflow.
In most cases a tube called a vortex finder extends downward from top center and acts as the overflow outlet path.
