Abstract

A feed and dewatering device for dewatering/squeezing/washing of fiber pulp etc. comprising one section (1) for inlet, one section (2) for dewatering/squeezing, one section (3) for adding and mixing of washing liquid, one section (4) for the final dewatering/squeezing and one section (5) for outlet of treated material. The dewatering in zone (2) exists between a converging screen basket and a diverging screw core and dewatering in zone (4) between a cylindrical screen basket and a diverging screw core.
