摘要： A rotary processor has enclosed processing passages defined by channels in the rotor and a stationary coaxial closure. At least one processing passage is used as a stabilizing passage and another as a metering passage, whose volume and cross section are less than the stabilizing passage. A feed of plastic or polymeric material enters the stabilizing passage and may be subject to fluctuations or disturbances arising in external upstream equipment or within upstream stages of the processor itself. Substantially all material in the stabilizing passage is diverted through a first transfer passage to an entrance into the metering passage. An adjustable metering (throttling) element allows a controlled first flow of material to be carried downstream through an adjustable gap between this metering element and the bottom of the metering passage. This controlled first flow is discharged for providing material having uniform flow or at least a marked reduction in such fluctuations and disturbances. The excess material which does not pass through the adjusted gap forms a recycled second flow which is returned back through a second transfer passage into said stabilizing passage for recycling. A modified embodiment shown as metering pumping apparatus includes pairs of stabilizing and metering passages sharing in handling throughput with adjustable throttling means for each metering passage. Interconnecting transfer passages equalize operation among these pairs. A transfer passage is also shown extending from an upstream processing passage to and past a metering passage to a stabilizing passage.

摘要： A multi-stage rotary processor particularly useful for processing plastic and polymeric materials. The multi-stage rotary processor includes a rotatable element carrying a plurality of processing channels and a stationary element providing a coaxial closure surface cooperatively arranged with the channels to provide a plurality of enclosed processing passages. Also associated with the stationary element are inlets, outlets and blocking members for each passage and arranged so that material fed to the passage can be dragged forward by the channel walls, and collected at the blocking member for discharge from a passage(s) of one stage to a passage of another. The geometry of the passage receiving material is selected to provide optimum processing efficiency, resulting in a processing rate capability for that passage greater than the rate at which material is supplied to the passage. Adjustable material transfer rate control means are arranged near the inlet of the material receiving passage so that the processing rate of the passage can be adjusted for coordination with the rate at which material is supplied to the passage.

摘要： Novel rotary processors including sealing means to control leakage of pressure and/or material between processing passages which are maintained at significantly different pressure levels. The processors comprise a rotatable element carrying a plurality of annular channels and a stationary element providing a coaxial closure surface operationally arranged with the channels to provide enclosed processing passages. Each passage includes inlet means, outlet means and a channel blocking member all associated with the stationary element and arranged and adapted so that viscous material fed to the inlet can be carried forward by the rotatable channel walls to the blocking member for discharge from the passage. The passages are interconnected by material transfer grooves formed in the closure surface.A sealing groove is carried by the rotor surface portions between two adjacent passages maintained at significantly different pressure levels, such as by evacuating one of the two adjacent passages, and is open to the clearance between the rotor and the closure surface. A gate at the inlet to the downstream pasasge pressurizes the material in the transfer groove interconnecting the two passages, and forces pressurized material in the sealing groove as it passes under the transfer groove. Helical grooves in the rotor portion on both sides of the sealing groove reinforce the pressure in the sealing groove and urge the material radially outward so that the material in the sealing groove contacts the closure surface about the entire circumference of the sealing groove, forming a continuous live O-ring seal in the clearance between the passages.

摘要： Novel and improved processes and apparatus for processing particulate materials which can be converted to the liquid state. Essentially, the process and apparatus involve feeding a particulate material to an annular processing passage for melting and controlled processing. The annular processing passage is provided by a rotatable element carrying at least one processing channel, and a stationary element which provides a complementary, coaxial surface arranged with the channel to provide the enclosed processing passage. Also associated with the stationary element are an inlet for feeding material to the passage, an outlet for discharging material, a material collecting end wall surface for the passage and a member or members extending into the processing channel providing a material restraining surface between the inlet and outlet and occupying a predetermined portion of the melt pool space between the end wall and the restraining surface. Rotation of the rotatable element establishes relative movement between the rotating inner channel wall surfaces and the restrained particulate material, causing only liquid (melted) material in contact with the rotating channel walls to be dragged forward to the end wall surface for controlled processing and discharge. Controlling the size of the melt pool space provides control of processing characteristics for the liquid material collected in the melt pool space.

摘要： Improved means for aligning processing members at various positions in processing passages of rotary processors. Essentially, the alignment means (or alignment elements) comprise a non-rotatable member positioned in the processing passage and shaped to at least partially interfere with flow of material in the passage. The shaped member is designed to perform certain processing functions on material in the passage such as blocking, collecting, mixing, spreading, restraining etc. The member is positioned so as to be non-rotative with the passage but is flexibly supported so as to "float" axially in the passage and is self-centering in the passage by hydrodynamic action.

摘要： Multi-screw, extrusion-compounding machines having co-rotating screw assemblies incorporating sets of modular mixing elements of non-symmetrical geometries with relatively large wing tip clearances. These sets of non-symmetrical modular mixing elements are removably mountable at any suitable axial locations along their respective rotationally-driven screw shafts for optimizing performance in relationship to particular plastic material and particular additives being compounded. The non-symmetrical geometries provide dynamic wedging pressurization for repeatedly propelling relatively large circumferential flows of the plastic material through large shear clearances. Due to the relatively large shear clearances, the plastic material is mixed at less elevated and more uniform temperatures than usually occurs with use of prior symmetrical kneading blocks or kneading discs. At less elevated temperatures most plastic materials exhibit increased viscosities. Thus, the resultant increased viscosities enable the plastic material to be processed at higher shear stresses for enhancing dispersive mixing, in spite of the relatively large clearances which are being utilized. Thus, operators of extrusion-compounding machines are provided with desirable flexibility in adapting them for enhanced performance in matching machine processing functions with the processing characteristics and parameters of plastic materials and additives being compounded.
