Cyclone separator is a type of sedimentation technique that works on the principle of centrifugal force rather than gravitational force. Thus, based on the fluid velocity, a cyclone enables the separation of all the particles or only the coarse particles can be removed, leaving behind the particles which are then carried away by the fluid.

In cyclone, cut diameter is defined as the diameter of a particle for which the efficiency cure has the value of 0.5, i.e. 50%. Cut diameter is one of the important indexes for evaluating dust performance in a cyclone separator. The smaller the cut diameter in a cyclone separator, the better is its dust performance.

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.
