ABSTRACT:
This invention relates to size reduction apparatus and particularly to a novel feed device thereof and method of feeding sheet material thereto. A first baffle is adapted to extend into the cutting chamber simultaneously towards the cutting rotor and a downstroke wall portion from which a bed knife is adapted to extend into cutting contact with knife means mounted on the rotor. Such construction, in effect, enables the simultaneous formation of a variable width sheet feed opening to the granulator as well as means for restraining a portion of already granulated material on the upstroke side of the rotor from contacting the sheet material as it is fed between the rotor and bed knife. A secondary baffle may in turn be disposed in contact with the first baffle so as to close a secondary or housing opening disposed between the first baffle and a pair of upwardly spaced feed rolls.
