するスクリユーデカンタ型遠心濃縮機。 It is equipped with a cylindrical bowl that is supported by hollow shafts fixed at both ends and rotates in one direction, and a screw conveyor that is arranged coaxially within the bowl and rotates in the same direction at a different rotational speed than the bowl. The solids are separated and sedimented from the solid suspension supplied into the bowl by centrifugal force, and transferred to one end of the bowl by the screw conveyor, where the solids concentrate and the remaining separated liquid are separated. The separated liquid is discharged from separate routes, and the separated liquid is discharged through a louver-type separated liquid screen provided at a position away from the end of the body of the screw conveyor. A screw decanter type centrifugal concentrator featuring:
