Wood-grained polymer board

An Underwater pelletizer for cutting extruded plastic into a flow of liquid. The pelletizer includes a cutter hub () carrying at least one cutter blade (), a cutter shaft () for rotationally driving the cutter hub, and a flexible torque converter () for connecting a motor to the cutter hub. In one embodiment, the torque converter has a first set of bushings () that is fastened to a face () of the cutter hub and a second set of bushings that is fastened to a face () of the cutter shaft. A shaft extension () can be configured to engage a motor shaft, the shaft extension having an Outer diameter having formed thereon a splined portion () and first () and second () sealing surfaces. A motor adapter () has a seal surface (). A water chamber plate () may also have a seal surface ().
