Publication number: 20100288681Abstract: A device including a hollow cylindrical body, first and second stationary coaxial annular screening screens disposed within the body, and a rotor within the body and positioned between the screens to conduct the slurry through the first screen and then through the second screen, the rotor being driven in rotation. The pulp slurry passes through a central entry pipe, radially outward and then upward along the inside of the rotor, further inward through a coarse screen cylinder, and then around the end of the rotor to pass between the outer surface of the rotor and the inner surface of a fine screen cylinder. The pulp slurry then finally passes outward through the fine screen cylinder. Coarse rejects, such as knots or other coarse material, are collected at the end of the coarse screening chamber and led away for further processing. Fine rejects are similarly collected at the end of the fine screening chamber, also to be led away separately for further processing.Type: ApplicationFiled: May 12, 2009Publication date: November 18, 2010Applicant: GL&V FIANCE HUNGARY KFT.Inventor: Brian J.
