A cutter hub pin drive mechanism and a quick disconnect hub for a pelletizer and a pelletizer having a cutter hub pin drive mechanism are provided. The pelletizer has a cutter hub that includes a cutter hub holder which is engaged with the pelletizer shaft through a plurality of drive pins. The drive pins ride in drive pin channels formed by grooves cut into an inner surface of the cutter hub holder and aligned grooves formed in the outer surface of the forward end of the pelletizer shaft. Also provided is a seal around the pelletizer shaft to prevent the egress of fines into the drive pin area, and a quick disconnect hub by which the pelletizer shaft can be readily disconnected from the cutting assembly to facilitate the removal of agglomerated polymer in the cutting chamber. |
