the wall of the hydrocyclone tube and this displaces the lighter phase which migrates toward the center where it forms a core. By controlling the pressure across the tube the core is forced to flow through the overflow and the heavier solids or liquid are directed to the underflow. The result is a process with typically a 2 3 second retention time.

The Top 5 Things You Need To Know About Hydrocyclones

Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point also called cut point or d50 will be. The separation point is the size at which a particle has a 50 50 chance of reporting either to the underflow or overflow. When the pressure is below the target pressure, the d50 will be coarser than desired.
