Hydrocyclone Operation, Hydrocyclone Selection, Dewatering ...

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.
