Abstract: A thermoplastic pelletizer providing enhanced pellet yields with reduced fines contamination. The pelletizer includes a cutting rotor and a feed assembly for feeding plastic to the cutting rotor. The pelletizer further includes two chutes, wherein a first chute arranged to collect pellets, and a second chute arranged to collect fines. A vacuum is drawn on both chutes to assist in the collection of both pellets and fines in their respective chutes. Compressed air is directed past the cutting rotor to the first chute to assist in moving pellets from the cutting rotor to the first chute.
