Abstract
The present disclosure relates to a size reduction apparatus such as a granulator and particularly to a novel feed assembly for such a granulator whereby thin plastic sheet material may be successfully granulated at high through-put speeds. The construction includes the use of a closed chamber mounted above the granulator chamber and having a longitudinally orientated feed slot therein, directly above which a pair of nip rolls are mounted so as to enable sheet material to be fed directly into the chamber of the granulating machine towards the rotor and in a generally radial direction thereto. The device is operated while the chamber thereof is at least partly full of partially granulated material. A baffle extending from the upstroke side of such slot is positioned so as to downwardly extend into the chamber and approaching the rotor thereof so as to deflect partially granulated material carried by the rotational movement of the rotor from contacting the newly entering sheet material so as to prevent deflection thereof away from the rotor.
