ABSTRACT:
A method and apparatus for treating a suspension of liquid, paper making fibers and undesirable rejects to remove a substantial portion of the rejects from the suspension. A cylindrical screen is utilized which has narrow slots on the order of 0.001 to 0.008 inch in width disposed normally with respect to the screen axis, and bars projecting from the inlet face of the screen and cooperating with rotating foils for creating a field of high intensity, fine scale turbulence adjacent the inlet face of the screen. This permits the paper making fibers to pass through the narrow screen openings but causes very small reject particles, which would pass through the larger openings of conventional paper making screens, to be removed without fractionation of the paper making stock or appreciable variation in the consistencies of the feed, accepts and rejects.
