摘要： An air lift pump for wet particulates has a plurality of transport tubes and air injectors disposed in a central column for transporting particulate matter from a lower elevation to a higher elevation. The central column has a closed top and an open bottom. Each tube has a lower, intake end, a lower first air injector and an upper second air injector. Each air injector is comprised of a housing disposed around an air injection section of the transport tube in which is mounted a first or second air jet, respectively. Compressed air is supplied to the first air injector via an air supply line and to the second air injector via an air supply line and the central column.

摘要： A method and apparatus in the context of a rotating conveying screw situated within a cylindrical housing which has an inlet port on one end of the cylinder and a discharge opening on the other end of the cylinder. A resistance plate is mounted transversely to the conveying screw near the discharge opening for corotation with the screw. The plate is mounted to define a discharge gap between the opening and the plate. A sleeve on the housing is employed to adjust the size of the gap between the plate and the opening. The resistance plate can be a flat disc, conical, or other shape, so long as it is effectively attached to and rotates with the screw. The helical screw is preferably supported at both ends by a bearing means. Breaker bars are mounted on the transverse plate and extend over the gap between the discharge opening and the plate. Breaker bars may also be mounted to the cylindrical sleeve and extend over the gap between the sleeve and the plate. In another aspect of the invention, a flow of steam or a hot fluid enters and/or leaves the interior of the screw, through the end of the screw near the discharge opening.

摘要： A high consistency pulp refiner of the type having a pressurized casing (12) containing opposed grinding discs (14,18) mounted for counter-rotation about a common axis (26) and between which material to be refined is introduced near the axis so as to move generally radially outwardly through an inner refining zone (40) between the discs while producing steam as a result of the refining action. The partially refined material and steam then move through a generally radially outer refining zone (50) between one of the discs (14) and a stationary grinding surface (54) situated generally radially outwardly of the other disc (18), whereupon the refined material and steam are discharged from the casing through a material outlet (62). A generally axially extending flow path (64) originates between the first refining zone (40) and the second refining zone (50), for diverting steam produced in the first refining zone away from the second refining zone while the partially refined material moves from the first refining zone to the second refining zone.

摘要： A refiner element (10) for the refining of fibrous material is provided with a comminuting surface of which at least a portion comprises an abrasive surface. The method of forming the refiner element (10) comprises casting a metal substrate (20) having a frontal surface (22), melting a relatively thin layer of the metal substrate on the frontal surface thereof to form a molten pool in the comminuting surface over the region thereof on which an abrasive surface is desired, depositing an abrasive material (38) into the molten pool formed in the metal comminuting surface (22) of the refiner element (10), and allowing the molten metal pool into which the abrasive material (38) has been deposited to solidify whereby the particles of abrasive material (38) are strongly bonded into the metal surface of the refining element to form the abrasive comminuting surface thereon. Most advantageously, the melting of a thin layer of the frontal surface (22) on the metal substrate (20) of the refiner element (10) is accomplished by directing unto the comminuting surface a laser beam (88) of sufficient intensity to melt the surface to a pre-determined depth.

摘要： The double tapered die mount defines a channel to support the die shoulder. No contact occurs between the die and die housing. The die shoulder is machined to be in generally congruent relationship with the channel shape of the die mount of the invention. In the prior art, the die shoulder is perpendicular to both the inner radial surface and the outer radial surface of the die mount. In the preferred embodiment, the die shoulder is tapered from the inner radial surface toward the die edge to define an inner die taper. The die shoulder also tapers from the outer radial surface to the die edge to define an outer die taper. The side walls of the channel defined by the die mount of the invention taper inwardly to be congruent with tapered surfaces of the die shoulder. The inner channel wall, i.e., the channel wall closer to the axis of rotation of the die, contacts the inner die taper. The outer channel wall, i.e., the channel wall farther from the axis of rotation of the die, contacts the outer die taper. The inner channel wall and the outer channel wall taper toward each other in the direction toward the base of the channel. The edge of the die shoulder does not contact the bottom of the die mount channel, and therefore, a gap exists between the bottom of the die mount channel and the die edge. Both radial forces and torque forces resulting from operation of the pelletizer are taken up by the mated tapered surfaces.
摘要翻译：双锥形模具安装件限定了一个支撑模具肩部的通道。模具和模具外壳之间不会发生接触。将模肩加工成与本发明的模具座的通道形状大致一致的关系。在现有技术中，模具肩部垂直于模具安装座的内径向表面和外径向表面。在优选实施例中，模肩从内径向表面朝向冲模边缘逐渐变细以限定内模锥度。模肩也从外径向表面到模具边缘逐渐变细，以限定外模锥度。由本发明的模具座限定的通道的侧壁向内逐渐变细以与模肩的锥形表面一致。内通道壁，即靠近模具旋转轴线的通道壁接触内模锥形。外通道壁，即距离模具旋转轴线更远的通道壁接触外模锥形。内通道壁和外通道壁朝向通道底部的方向朝向彼此逐渐变细。模肩的边缘不接触模具安装通道的底部，因此，在模具安装通道的底部和模具边缘之间存在间隙。由造粒机的操作引起的径向力和扭矩力均由配合的锥形表面吸收。

摘要： A method and apparatus in the context of a pellet former (10) that is integral to an annular gap extruder/expander (11). A housing (30) is disposed around the annular gap extruder outlet end. Material is received from annular gap (37) on the face of a rotating disc (14) and, upon expansion, is directed into a roller area (43) by feed plows (23) or a screw flight (42). Pellet rollers (24) rotatably mounted on the disc push the material through a ring pellet die (22) disposed around the roller area. Cut off knives (25) attached to the disc cut the material into pellets as it exits the pellet die.

摘要： In an apparatus (10,100,300,400) for refining a low consistency fibrous slurry, which includes a plurality of refining zones (38,40; 188,128; 324,334; 411,413) within a casing, the improvement comprises providing a unique discharge flow path from each refining zone to a respective unique discharge line (56,58; 130,142; 308,310; 411,413) out of the casing, and means (57,59; 141,143; 344,346; 432,434) for differentially adjusting the flow rate in each discharge line. In accordance with the preferred embodiment of the invention, a divider (42,132,340) is provided between the casing and the rotor member, thus dividing the discharge between the two refining gaps, into two separate flow streams. The first and second gaps are monitored in any conventional manner. Under operating conditions, the flow control valves are adjusted for combined flow from the refiner casing as required by the production demands. However, the relative positioning between the two valves is adjusted until the refining gap measurements show equal gaps (within a pre-established tolerance) in the two refining zones.
