  • The Top 5 Things You Need To Know About

    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. Higher pressure than the target will send more fines into the underflow, thereby making a finer d50 than desired.

Cleaned water exits through the underflow.
