摘要：
A casing has a pulp slurry inlet, a reject outlet and an accept stock outlet and accommodates a rotor. The rotor has a hollow cylinder with scraper blades at its outer periphery. A screen plate is disposed outside of the scraper blades to provide between them a passage facing to the screen plate. The hollow cylinder is formed with pulp slurry outlets. Rotation of the hollow cylinder causes the pulp slurry to be circulated outside and inside of the hollow cylinder, so that separation of the pulp slurry into accept stock and reject is repeatedly carried out by the screen plate.
