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.

Feed device for sheet granulator and method of feeding same

The present invention relates to a rotor construction and particularly one in which the rotor includes a plurality of open-faced knife sets each having at least a pair of longitudinally spaced plates. At peripherally spaced locations between said plates, relatively heavy material contacting blocks are disposed. The blocks in turn provide a seat for a knife blade. Material fed to the chamber of a granulating machine in which such rotor is mounted, is contacted by the plates and the blocks with a pummelling action and by the knives in a cutting action. The material so pummelled and cut is thereafter free to pass immediately into open face portions or pockets disposed between the plates of each knife set. The material contacting faces of the plates and the blocks are provided with a hard faced surface. The rotor is referred to as being of 'club-foot' construction.
