Method of regulating the overflow from a cyclone ...

A method of regulating the overflow from a cyclone, hydrocyclone or similar device (1) comprises the steps of passing the overflow (1C) to the main inlet (3C) of a fluidic valve (3) and passing at least a proportion of the underflow (1B) from the device (1) to the control inlet (3B) of the said fluidic valve (3).

Hydrocyclone | EMIS

The working principle of Xinhai hydrocyclone is centrifugal sedimentation, when two phases (or three phases) mixed liquid is fed into hydrocyclone by a certain pressure liquid and produces strong three-dimensional-elliptic rotational movement. Due to the different density of particles, the centrifugal force, the centripetal buoyancy and drag force is different.
