Abstract
An adjustable sectioned water flow guide stationarily mounted in the water box of an underwater pelletizer to adjust the flow of pressurized water through the water box in order to accommodate a range of variable process requirements, such as pellet size, water flow, water temperature, melt flow, etc., while preventing pellet distortion and die hole freezing. The length and surface configuration of the water flow guide may be readily adapted through selection of an appropriate number of grooved or ungrooved sections to optimize fluid flow for particular pelletizer applications.
