LW Series Decanter Centrifuge

Centrifugal sedimentation is the working principle of this centrifuge, it can separate two phases (suspended solid liquid and liquid), solid phase is pushed out by spiral continually; this equipment is a constant and high effective equipment which used in separating solid-liquid. 

After the material enters the inner cavity of the screw ejector from the feeding tube, the material flows to the drum wall through the discharge port due to the high speed rotation. The light and heavy phases of the constituent materials are rapidly deposited on the inner wall of the drum due to different centrifugal forces, while the light phase is attached to the surface of the heavy phase, forming a layer interface between the light and heavy phases. As the heavy phase deposition increases, the spiral blade end enters the heavy phase deposition layer. At this time, the drum propeller rotates at the same speed at a high speed, and there is a certain difference in the rotational speed. This relatively low rotational speed pushes the solid phase particles to the small end discharge port. The light phase forms a channel through the spiral and flows to the large end liquid phase port, and the liquid phase overflow radius is controlled by the regulating plate.
