ABSTRACT:
The disclosure concerns a rotor for use in a pulper for forming a pulp suspension through rotation of the rotor in a pulp container. The rotor is generally conically shaped. Around the exterior of the rotor wind a plurality of helical conveyor elements. Each conveyor element includes a flat surface that is oriented obliquely at an acute angle to the axis of the rotor, and the angle of the conveyor element surface with respect to the rotor axis decreases upwardly along the rotor. On the peripheral edge of the conveyor element at the bottom of the rotor, an additional vane is defined which extends outwardly of the conveyor element. The vane is tilted at a different angle to the rotor axis than the conveyor element and is typically more nearly perpendicular to the rotor axis. The outer peripheral edges of the conveyor element and of the additional vane are sharpened to define cutting edges and may be additionally clad.
