Abstract: A method and apparatus for underwater pelletizing and subsequent drying of polyethylene terephthalate (PET) polymers and other high temperature crystallizing polymeric materials to crystallize the polymer pellets without subsequent heating. High velocity air or other inert gas is injected into the water and pellet slurry line to the dryer near the pelletizer exit. Air is injected into the slurry line at a velocity of at least about 200 m3/hour. Such high-speed air movement forms a vapor mist with the water and significantly increases the speed of the pellets into and out of the dryer such that the PET polymer pellets leave the dryer at a temperature sufficient to self-initiate crystallization within the pellets.

Abstract: The invention is directed to a device for converting free-flowing feed material (43), for example, foils, fibers, foam products, powders, and the like of organic and/or inorganic materials into granules, agglomerates, pellets, green compacts, and the like by applying pressure with a cylindrical compression chamber (17), which is arranged around an axis (1). At its periphery, the compression chamber (17) is confined by a ring element (18) with passage openings (19), and it accommodates a pressure element (10) that rotates around the axis (1) in the direction of rotation (27). The feed material (43) is axially conveyed to the compression chamber (17) and is radially supplied to the ring element (18) by the pressure element (10). The pressure element (10) includes at least one pressing blade (9), which extends to and interacts with the ring element (18), the front flank (28) of said pressing blade in the direction of rotation (27) being curved such that between pressure arm (9) and ring element (18), a narrowing compression zone (30) is formed, the end of which is formed by a pressure piece (29, 42). Due to the thus fixedly defined geometry of the compression zone, various process parameters, for example, pressure, temperature, and viscosity of the feed material, cannot be influenced while being processed. The remedy of this disadvantage provided by the present invention is such that the segment of the pressing blade (9), which is positioned in front of the pressure piece (29, 42) in the direction of rotation (27), and which forms the compression chamber (30), is at least in part formed by a shape component (31, 40), which is detachably connected to the pressing blade (9), the spine of which (34) determines the contour of the compression zone (30).

Abstract: A method and apparatus for underwater pelletizing and subsequent drying of polyethylene terephthalate (PET) polymers and other high temperature crystallizing polymeric materials to crystallize the polymer pellets without subsequent heating. High velocity air or other inert gas is injected into the water and pellet slurry line to the dryer near the pelletizer exit. The slurry line has a substantially straight component, and air is preferably injected at the end of the straight component nearest the pelletizer exit and in a direction substantially coincident with the axis of the straight component. The air injection significantly increases the speed of the pellets into and out of the dryer such that the PET polymer pellets leave the dryer above at least 135° C., and preferably above 145° C., to self-initiate crystallization.

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.

Abstract: A die and a die assembly are disclosed for use in association with an underwater pelletizer. The die has unique coiled heating elements which allow for uniform heating of the extrusion orifices which pass through the die, reducing or eliminating polymer solidification within the die, thereby allowing the manufacture of uniform pellets of a specific geometry. The heating elements are contained within the die plate of the die, and in a preferred embodiment occupy annular grooves formed therein which are concentric with the extrusion orifice pattern. The die assembly includes thermally-insulating adaptors and gaskets which cover the annular grooves containing the heating elements.

A material feeding system is connected to the hollow chamber. An agglomerating vane arranged in the hollow chamber rotates in a direction of rotation about a longitudinal axis of the hollow chamber. The agglomerating vane has a front side in the direction of rotation. The front side, the front and rear wall elements, and the perforated die define a revolving plasticizing chamber. The front and rear wall elements have inner surfaces facing the hollow chamber and at least one of the inner surfaces has profiles running from an inner area of the inner surface to an outer area of the inner surface for transporting the feed material.
