Abstract
A rotary granulator having a rotor positioned coaxially within a cutting chamber defined by a multi-perforate cylindrical screen mounted on an end plate with a fixed bed knife projecting into the cutting chamber in position to cooperate with a rotor knife in cutting up stock introduced axially into the cutting chamber through the end of the chamber opposite the end plate. The rotor includes a hub adjacent the end plate and at least two spaced rotor arms projecting from the hub parallel to the cutting chamber axis with the rotor knife mounted on a rotor arm. An annular rotor bearing member is mounted on the ends of the rotor arms opposite the hub within a fixed bearing member; the two bearing members comprise an outboard guide/support bearing for the rotor, affording support for the rotor but allowing unimpeded axial feed into the cutting chamber. A housing around the screen defines a separation chamber for granulated stock passing through the screen, with egress passages from the separation chamber into an annular exit chamber housing a rotary impeller that propels a stream of air and granulate through the cutting chamber, the screen, the separation chamber and the exit chamber, and out through a discharge opening.
