BFN 6897 DUAL FLOW SCREENING APPARATUS Abstract of the Disclosure A pressurized screening device has an-inlet arrangement by which a feed slurry is directed to a central portion of a screening chamber, a plurality of chevron-shaped rotor foils are mounted for rotation near the inner surface of a cylindrical screenplate to split the flow of the feed slurry into separate flow portions directed toward opposite ends of the screening chamber, and separate reject chambers are provided adjacent its opposite ends of its screening chamber. The chevron-shaped foil structure enables the screening device to operate as if it were two smaller screening devices and to remove efficiently both light and heavy impurities from the feed stock.
