20080259717 | Extruder - An extruder comprises a displacement part with a housing, inside of which at least one screw shaft is housed and which is provided, at one end, with a material entry opening for the material to be processed and, at the other end, with a material outlet opening for the processed material, and with an intermediate opening between the material entry opening and the material outlet opening for discharging gas from the displacement part. A material retaining device is connected to said intermediate opening and has at least one screw shaft inside an intermediate housing. This screw shaft extends from the intermediate opening to a gas discharge opening in the intermediate housing and conveys material entering the intermediate housing back into the displacement part. To this end, the screw section of the screw shaft facing the displacement part has a direction of thread that returns into the displacement part, and the screw section of the screw shaft facing away from the displacement part has an opposite direction of thread. | 10-23-2008 |

20110292755 | KNEADING APPARATUS AND METHOD FOR KNEADING RUBBER-BASED COMPOSITION USING THE SAME - A kneading apparatus includes a barrel having a cylindrical chamber; a screw assembly rotating in the chamber so that a material to be kneaded is extruded in the axial direction by the rotation, the screw assembly including a screw section having helical blades and a kneading blade section in order to allow the material to flow into the clearance between the inner wall of the chamber and the kneading blade section, and to apply shearing forces to the material; a metering feeder for feeding the material at a substantially constant volumetric or gravimetric rate into the chamber; an injecting device for injecting a heat-removing medium into the chamber; and a discharging device for separating the heat-removing medium from the material and discharging the heat-removing medium from the chamber. A kneading method using the kneading apparatus is also disclosed. | 12-01-2011 |
20120081989 | APPARATUS AND METHOD FOR PLASTIC EXTRUSION - An object of the invention is to improve capacity of process and not require a vent portion by an upper polygonal groove and a transition portion provided to a transport cylinder. | 04-05-2012 |
20120106288 | VACUUM KNEADING AND DEAERATING DEVICE - Disclosed is a vacuum kneading and deaerating device capable of conducting an uniform and sufficient kneading treatment and a sufficient deaerating treatment with a high efficiency for a paste material contained in a cylindrical paste container. | 05-03-2012 |
20120250447 | CLAY MIXING APPARATUS - A clay mixing apparatus includes a mixing chamber, a rotor arranged within the mixing chamber, a drive unit arranged to rotate the rotor, an ejecting unit, a pressure reducing unit; and an exhaust flow path. The rotor includes a shaft rotated by the drive unit, an extruding member and a mixing member. The mixing member includes a plurality of arms and a plurality of blades arranged at tip ends of the arms. The exhaust opening is opposed, in a radial direction about the center axis, to a portion of the mixing member lying near the extruding member and/or a portion of the extruding member lying near the mixing member. | 10-04-2012 |
20130135957 | DEVICE FOR MIXING BONE CEMENT AND METHOD FOR MIXING BONE CEMENT AND USE OF THE DEVICE - A device automatically mixes bone cement and has two separate plunger space sections with a gas feed and a gas outlet, which are separated from each other through a plunger. A blocking organ is provided in the plunger and can be switched at the turnaround points of the plunger path. Suitable connecting facilities connect the plunger to a mixing facility that is arranged in a mixing vessel. Alternating build-up of a pressure difference and pressure equalisation in both plunger space sections causes the plunger to move up and down. The plunger motion effects a simultaneous up-and-down motion and rotation of the mixing facility. | 05-30-2013 |
20130182528 | MIXING DEVICE FOR PREPACK VACUUM CEMENTING SYSTEM, VACUUM CEMENTING SYSTEM, AND METHOD - A mixing device, for a mixable material, has at least one cartridge and a closure piece.
