    摘要: A centrifugal pellet dryer screen (540) especially adapted for drying polymer pellets and micropellets includes an exterior or outer support screen (542), an inner screen (546) of an irregular or rough surface, and an optional middle screen(s) (544) sandwiched between the outer support screen and the inner screen. The screen layers are in intimate contact and the multi-layer screen assembly produces drier pellets and micropellets exiting the dryer. Plugging of the dryer screens and banding of the pellets or micropellets are significantly reduced.

    摘要: A cutter hub and blade assembly for cutting polymer strands extruded from a die face in a pelletizer has cutter blades mounted on the cutter hub at a steep angle. The blades are beveled along a portion of their leading edge to form a blunt cutting edge or surface to the blades which is generally perpendicular to the die face. By beveling the leading edge of a blade supported at a steep angle to form a blunt cutting edge, the bottom surface area of the blade in contact with the die face can be significantly reduced. The reduced contact area provides several advantages including a clean cut of the pellets and a faster blade grinding when seating the blades to the die face.

    摘要: An apparatus and method for the pelletization of waxes, wax-like and other materials having a sharp melt point include a vessel for forming the wax into a hot molten material. A heat exchanger then cools the molten wax to a temperature just above its melt temperature. The cooled liquid wax is fed to an extruder which further reduces the temperature and mixes the liquid wax into a thoroughly mixed extrudable solid wax. The solid wax is then extruded through die orifices of a die plate into a cutting chamber, and a rotary cutter cooperating with the die face of the die plate cuts the extruded solid wax strands into pellets. The die plate, cutting chamber and rotary cutter can have the same structure as an underwater pelletizer, but operating without water or liquid as a dry face pelletizer. The thus formed wax pellets drop out of the cutting chamber by gravity through an opening in the bottom thereof.

    摘要: A melt cooler and valving system for an underwater pelletizer has a diverter valve that facilitates multiple modes of melt processing. The cooler has a cooler inlet line that conveys the melt to the cooler, and a cooler outlet line that conveys the cooled melt from the cooler. The diverter valve is configured to convey the melt to and from the cooler during a cooling mode of operation, to convey the melt around the cooler during a bypass mode of operation, and to drain the melt from the cooler and the diverter valve during a drain mode of operation. The diverter valve is compact and therefore contains a minimum of product inventory. The valve is streamlined and direct in its bypass mode, and includes a drain capability to allow for faster, easier cleaning of the process line, which in turn provides a fast changeover time with less lost product.
