摘要： A screw extruder (10), including a barrel (18) having a bore (26) which defines an inner surface (24). At least one extruder screw (28) is positioned within the bore (26), each screw (28) further including a central shaft (34) and at least one screw flight (30). Each screw flight (30) further includes a front pushing face (36) and a rear face (38). The profile (40) of each front pushing face (36) acts with the inner surface (24) of the barrel (18) to form a progressively narrowing passage (46) through which material is forced into multiple regions of high elongational and shear stress (48) which act to break down agglomerates of material and thus dispersively mix the material.Also presented is a screw extruder (100) having a single screw (28) which includes dispersion disks (102) which are rotationally offset from one another and whose design is not constrained by interaction with a second disk, which provides improved distributive and dispersive mixing.Also presented is a method of extruding material using a screw extruder (10) having pushing face (36) profiles (40) which form progressively narrowing passages (46) in conjunction with the barrel (18) inner surfaces (24) to provide improved dispersive mixing.

摘要： A polymer-extruder screw has a mixing section with relatively deep channels between flight lands at a proximal end, progressively shallower channels with a progressively larger screw core of a central transition section, and finally a metering section having a plurality of at least three pressure channels juxtaposed helically between flight lands having channel interruptions comprised of helical inclines and constant-radii tops in helical progression to a distal end of the extruder screw where the pressure channels end with equal depth at an interface with a metering gate of an extruder. The pressure channels can be symmetrical or asymmetrical in angles of incline and decline at opposite helical sides of the channel interruptions for optimizing channel depths, for positioning of maximum channel depths in relation to tops of channel interruptions, for equalizing channel depths at the distal end of the extruder screw and for optimizing incline and decline advantages for polymers with different characteristics. Helical degrees of channel-interruption cycles can be different for different polymers. The screw core in the mixing section can be graduated in diameter and distance between flight lands can be designed as required for different polymers.

摘要： A plasticating apparatus having a barrel and a screw rotatably disposed therein. The screw has a mixing section including a helical conveying flight to form a helical passage for transporting resinous material along the screw. The mixing section further includes a helical, zig-zag barrier flight spaced from the conveying flight to divide the helical passage into channels of varying cyclic depth in the helical direction of the channels. The portions of minimum depth of the channels define wave crests which are helically displaced from each other. The barrier flight has a first section converging toward one side of the conveying flight, and a second segment diverging away from the same side of the conveying flight. The plurality of first and second segments repeat throughout the mixing section.

摘要： An extruder for processing wood particles, shavings or sawdust is particularly useful for the production of a refined product exhibiting a large number of separated, individual fibers each of a relatively long length as is desirable in the production of a fiber core for a composite particle board. The extrusion apparatus comprises an elongated barrel and a flighted screw rotatable within the barrel, with the final downstream section of the screw being of a configuration to sequentially present three processing zones each having a compression region, a restricted region and a decompression region. The three processing zones of the final screw section cooperate with a compression region and restricted region formed in the final head section to choke the advancement of wood materials through the extruder sufficiently to enable satisfactory processing of the same without the use of a final die or restricted orifice disposed on the outlet of the extruder barrel. In particularly preferred forms, restriction elements in the form of rectangular bars are disposed across the grooves of the screw and grooves of the head in the restricted region, and the bars are oriented in acute angular relationship relative to each other in scissors-like fashion to promote rolling and twisting apart of the fibers while maintaining the longitudinal integrity of the same.

摘要： In a resin moulding screw provided with helical flight and valley, the bottom surface of valley is divided into a plurality of portions along a dividing line, and the divided portions are alternately displaced in the radial direction to form wavy contours. Barriers are provided to cross the dividing line to form dams which prevent intercommunication of the valleys at the bottom of the screw groove to prevent decrease of the thrust pressure along the flight for efficiently blending and melting solid and molten resins.

摘要： A heating device having a screw rotatable within a barrel therefor, such as a part of an extruder, especially constructed to circulate and heat a granular or particulate work load of fusible material while still in its particulate condition. The essential purpose is to heat the material to a uniform temperature just under plasticization in preparation for entering melting apparatus, such as a downstream melting section of an extruder. The screw has a core and a main thread defining a main channel in which the portions of the core surface extending side-by-side longitudinally of the channel deviate from an average core diameter throughout the length of the heating device to circulate the work load transversely of the channel and to heat the work load while in a granular condition.

摘要： An extruder conveying screw comprising a core having two helical flights thereon, the first of which extends between opposite ends of the screw to define a helical channel and the second of which extends generally across the channel over a portion intermediate the length of the screw, and a casing around said screw characterized in that said second flight is terminated at its upstream end in spaced relationship to the wall of the first flight and further in that the second flight is provided with a groove across its peripheral surface adjacent and parallel to a line of junction between the first and second flights at the downstream end of the latter, said groove having a depth such as to provide a clearance of between 0.060 and 0.090 inches between the base of the groove and the casing.
