A mixer vehicle comprises a chassis and mixer drum coupled with the chassis. The mixer drum includes a first cylindrical inner volume and a second cylindrical inner volume. The first cylindrical inner volume and the second cylindrical inner volume are fluidly coupled with each other at passageways positioned at both ends of the mixer drum. The mixer drum further comprises a first mixer screw positioned within the first cylindrical inner volume and a second mixer screw positioned within the second cylindrical inner volume. The first mixer screw and the second mixer screw are configured to be driven to rotate to drive a slurry material between the first cylindrical inner volume and the second cylindrical inner volume to mix the slurry material.

The invention relates to a process of manufacturing a dental milling block with a homogeneous color and/or translucency gradient. This process comprises the steps of providing a mold with a cavity having a z-direction and an x/y-direction, filling the cavity partially with a first powder up to a height H1, the first powder having a volume VP1 with a top and bottom surface, introducing a second powder on top of the first powder up to a height H2, the second powder having a volume VP2 with a top and bottom surface and, the top surface of the first powder being in contact with the bottom surface of the second powder and forming an intermediate region, providing a mixer unit with at least one rotatable mixing element, introducing the rotating mixing element in z-direction into the intermediate region, mixing the powder located in the intermediate region by rotating the mixing element, removing the rotating mixing element from the powder, compacting the powder, optionally applying heat to the compacted powder, the first powder differing from the second powder by its physical properties and/or chemical composition and/or color. The invention also relates to a process of producing a dental restoration using dental milling block obtainable according to this process.

A method in which a stream of dry cementitious powder from a dry powder feeder passes through a dry cementitious powder inlet conduit to feed a first feed section of a fiber-slurry mixer. An aqueous medium stream passes through at least one aqueous medium stream conduit to feed a first mixing section the fiber-slurry mixer. A stream of reinforcing fibers passes from a fiber feeder through a reinforcing fibers stream conduit to feed a second mixing section of the fiber-slurry mixer. The stream of dry cementitious powder, aqueous medium stream, and stream of reinforcing fibers combine in the fiber-slurry mixer to make a stream of fiber-cement mixture which discharges through a discharge conduit at a downstream end of the mixer.

A bone filler mixing and delivery device includes a mixing section adapted to mix components to form bone filler. A syringe barrel is coupled to the mixing section and has an opening through which the bone filler can be dispensed. A controllable portal can be manipulated to open a flow path between the mixing section and the syringe barrel. A plunger assembly is adapted to extend telescopically in an axial direction through the syringe barrel to dispense the bone filler through the opening.

A high shear mixing device is provided. The high shear mixing device comprises a first screw kneader and a second screw kneader; a first rotation driving mechanism configured to rotate the first screw kneader and a second rotation driving mechanism configured to rotate the second screw kneader; a revolution driving mechanism including the first rotation driving mechanism and the second rotation driving mechanism rotatably installed therein; a driving mechanism body including the revolution driving mechanism installed therein; and a mixing tank. Each of the first screw kneader and the second screw kneader comprises a shaft having one end connected to the rotation driving mechanism; and three or more blades having one end fixed to the shaft and having a helically curved body along the longitudinal direction of the shaft, and the first and second screw kneaders rotate in opposite directions with their blades overlapping each other.

A device for mixing or blending the contents of the device into a liquid or semi-liquid. The device includes a bottle body, a bottle lid connected to a top end of the bottle body, and a mixer located within the bottle body. The mixer may be powered by a motor or by a manual crank turned by a user.

The invention relates to mixing elements that have a larger number of basic geometric periods per section and an improved dispersing effect for multi-shaft screw extruders comprising screw shafts that co-rotate in pairs. The invention further relates to the use of the mixing elements in multi-shaft screw extruders, a corresponding screw extruder comprising the mixing elements, and a method for extruding kneadable materials.

An injection device is provided for repairing biological tissues and comprises a body, a chamber, an exterior tube, and a screw rod. The chamber is connected with the body and used for accommodating a repairing material. The exterior tube is connected with the chamber. The screw rod is disposed inside the chamber and the exterior tube. The threads of the screw rod disperse the repairing material. By using the threads of the screw rod and a driving force originating from the end of the screw rod, the repairing material is delivered into an organism.
