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.
