    摘要: A restored metallic extrusion processing element comprises a tubular metal core around which is consolidated a powdered metal extrusion component that includes metallurgically bonded interior shell and exterior working portions. The interior shell portion covers the core and is characterized by a first multiple-crystalline microstructure, and the exterior working portion is characterized by a second multiple crystalline microstructure of densified powdered metal particles. The exterior working portion has an outside surface including outer working surface features that extend along the length of the extrusion processing element. A bond interface of metallurgical type defines a crystalline microstructure boundary between the first and second multiple-crystalline microstructures.

    摘要: An extruder (20) is specifically designed for the production of animal feed products (e.g., aquatic feeds) containing substantial quantities of low-cost fibrous materials, such as rice byproducts, at high production rates. The extruder (20) includes an elongated barrel (22) with a screw assembly (24) within the barrel and an endmost extrusion die assembly (34). The screw assembly (24) includes an inlet screw assembly (42) and a processing screw assembly (44). The assembly (44) includes screw components (50-56) of differential pitch to present a long pitch inlet section (64) and a tight pitch discharge section (68). Materials passing through the screw assembly (24) are successively subjected to high levels of steam injection (STE) followed by high levels of friction and shear (SME), so that the STE/SME ratio is at least about 6/1.

    摘要: A novel barrier screw scientifically designed with new structural features that eliminate the shortcomings of the previous barrier screws and further improve their performance. The important new structural features include a structure of originating the barrier flight without creating any dead-spot while maintaining a constant solid channel width, a structure of terminating the barrier flight without creating any dead-spot while assuring good melt quality, a melt channel structure of avoiding excessively deep channel depth while assuring sufficient melt conveying capacity, and a solid channel structure of avoiding excessively large channel area with shallow channel depth while assuring good melt quality.

    摘要: A method of extending the life of an extruder screw by affixing tiles of wear-resistant material along the crest of the extruder screw flighting threads, and optionally grinding the hardened material to remove any sharp edges. In another configuration of the present invention, plates of wear-resistant material are secured to the leading edges of the extruder screw threads to further prolong the life of the extruder screw.
