    Abstract: Apparatus for mixing a material contained in a vessel comprises one or more flow channels and at least one pair of first and second members which are coaxially mounted one within the other about an axis of rotation such that their facing surfaces curve around the axis defining a chamber therebetween. At least one of the first and second members having a non-circular curvature, the first and second members being rotatable relative to one another about the axis to thereby produce a pumping force to force material through said flow channels. The radially outermost of said first and second members moves to a wall of the vessel relative to stress and displace material present between the mixing apparatus and the wall of the vessel.

  • Patent number: 6562763
    Abstract: A drilling fluid homogenizer and method of homogenizing drilling fluid which produce a non-clogging homogenized drilling fluid at a high throughput, in an open-loop process. The non-clogging homogenized drilling fluid is capable of being created at high rate so that the non-clogging homogenized drilling fluid is available on demand to eliminate halting of drilling operations. The drilling fluid homogenizer is coupled in series with the closed-loop designed drilling fluid system and is adapted to homogenize water-based drilling fluid and other drilling fluid types, such as, synthetic drilling fluid during drilling operations on demand.

  • Publication number: 20020089892
    Abstract: A portable mixing device for quickly and efficiently combining dry constituents with water to form a mix having a thin batter consistency and no unmixed material. Mounted on a wheeled, pivoting frame, a single individual can use the device to mix the material and pour it in the proper location. The device includes a cylindrical mixing drum and agitation tool mounted within the mixing drum. The agitation tool includes a motor and housing, a drive shaft, wiping assembly, and mixing assembly. The stationary wiping assembly, which extends downward into the mixing drum co-mingles so as to pass closely between and among the blades of the rotating mixing assembly such that the flexible edge portions of the wiping assembly blades are in intermittent contact with the blades of the mixing assembly. The “wiping” action of the wiper assembly on the mixing assembly insures complete and efficient agitation and mix of materials.

  • Patent number: 6123445
    Abstract: A mixer for dry powder, very fine or granular materials and a liquid, e.g., mortar or cement and water, includes a dynamic input mixing stage, a static output mixing stage and a transition tube connecting the two stages in a manner which isolates the two stages from one another. The input mixing stage includes a hopper for receiving the mortar and a horizontal metering screw having a detachable mixing auger. The auger mixes the dry mortar, while the metering screw moves the mixed mortar through a discharge aperture in the hopper and into the transition tube. The metering screw extends into the transition tube for further displacing the dry mortar into the output mixing stage which includes a mixing tube having a fixed internal baffle assembly and an auger disposed along its length. A source of water is connected to the mixing tube for forming a mortar-water slurry.

  • Patent number: 6110432
    Abstract: The disclosed apparatus includes a stator and a rotor disposed for rotation within the stator. An inner wall of the stator defines one or more collider chambers. Rotation of the rotor causes movement of fluid disposed between the rotor and stator and establishes a rotational flow pattern within the collider chambers. The fluid movement induced by the rotor increases the temperature, density, and pressure of the fluid in the collider chamber.
