ABSTRACT:
A channeled pulp rotor for use in a generally cylindrical or tub shaped pulper apparatus to make a slurry out of a mixture of solid and liquid materials for such things as paper making includes a rotor hub having at least one vane extending radially from a central axis of rotation of the rotor hub. The vane defines an impact surface between opposed top and bottom surfaces for impacting the solid materials upon rotation of the rotor and the impact surface defines a feed channel. The bottom surface defines a defibrating channel continuous with the feed channel so that materials flowing along or positioned in front of the rotating impact surface flow into the feed channel and continue from the feed channel to flow into the defibrating channel. In alternative embodiments, the feed channel and defibrating channels are eccentric to the axis of rotation of the rotor so that entries of the feed channel and defibrating channel are closer to the axis of rotation than exits of the channels. Centrifugal forces generated by rotation of the rotor act on the solid materials to force them through the feed and defibrating channels where they are sheared by cutting edges of a non-rotating plate adjacent the defibrating channel as the vanes rotate with the rotor hub.
