ABSTRACT:
An apparatus for pulping paper making stock at high consistencies which includes a rotor body having a plurality of vanes extending generally radially outwardly therefrom and a feed screw mounted centrally of the rotor body and extending upwardly therefrom along an axis of rotation of the rotor body. The feed screw includes a conical body having a base with a periphery adjacent root portions of the rotor vanes and at least one helical flight extending along the length of the conical body and, in one embodiment, has a tapered end which is located adjacent a vane root. The rotor body and feed screw are mounted for rotation in a center portion of the bottom wall of a tub for holding paper making stock such that, when the rotor is rotated, the conical body and helical screw guide material contacting the feed screw downwardly and outwardly to contact the rotor vanes which impel the stock toward the side wall of the tub with sufficient force to climb the wall.
