  • Patent number: 9821281
    Abstract: A mixing assembly includes a main flow conduit having an inlet end and an opposite outlet, a source of pressurized air at the inlet end, a container of stucco in fluid communication with the flow conduit, and a source of water in fluid communication with the flow conduit between the outlet and the container. The pressurized air draws stucco from the container into the flow conduit, and also draws water into the flow conduit to form an atomized slurry.

  • Patent number: 9643799
    Abstract: A pneumatic conveyor is operable to convey fine material and includes a pressure vessel and a pneumatic injection port. The pressure vessel presents a chamber operable to receive fine material and to be selectively pressurized with air to pressurize and convey the fine material. The pressure vessel includes an inclined wall that extends upwardly relative to an outlet, with fine material in the chamber being collected by the inclined wall and urged toward the outlet. The injection port fluidly communicates with the chamber, with the injection port located adjacent the outlet to inject compressed air into the flow of pressurized fine material.

  • Patent number: 8696190
    Abstract: The invention relates to methods and apparatus for a vibration-free placement of the concrete and for placement and enforced speed inertial compaction of the concrete under a high pressure. The method permits to optimize the values of the compaction factor of the concrete mix being placed without vibration. Whereupon, in the case of variation assigning and implementing (adjusting and optimizing) the integral indices of the mix, and/or the plume modes, and/or the space medium characteristics, increasing the concrete strength in early time of the concrete curing, increasing the width of the placed and compacted mix in one step of concreting, reducing the mix losses in the case of placing with compacting the concrete mix.

  • Patent number: 6354726
    Abstract: The invention relates to a mixing and conveying device for mixing and subsequently conveying semifluid materials, in particular mortar and concrete. The device comprises a compressor for generating compressed air, and a mixing vessel connected to a conveying conduit and an agitator gear. The mixing vessel is charged with the material to be mixed and conveyed, and compressed air is admitted into the mixing vessel for discharging the semifluid materials through the conveying conduit. The agitator gear is driven by at least one compressed air motor that is supplied with a proportion of the compressed air generated by the compressor.

  • Patent number: 5664881
    Abstract: A drum mixer is provided with a rotatable cylinder in which aggregates, reclaimed asphalt pavement and liquid asphalt are mixed to produce an asphaltic composition. The drum cylinder includes a first region, in which virgin aggregate is heated and dried by heat radiation and the stream of hot gases produced by a burner flame flowing in countercurrent flow to the aggregate itself to establish a highly beneficial heat transfer relationship. A second region doubles as combustion and mixing zones. In the mixing zone the reclaimed asphalt pavement and liquid asphalt is added and mixed with the aggregates. The combustion zone is formed along the center of the mixing zone by an elongated combustion assembly disposed along the central axis thereof. The combustion assembly and chamber extend from the discharge end of the drum through the mixing zone to the heating and drying zone to segregate the hot gases from the asphalt, thereby preventing degradation of the final product.

  • Patent number: 4708745
    Abstract: A process for the preparation and immediate use in situ of ready to use blends of structural material, such as plaster, mortar, stucco, tile adhesive or similar blends, which, in contrast to the usual methods does not use as a raw material a dry mixture of the three main components binder, filler and additives. Instead a dry mix of binder and filler is prepared at the building site, and an aqueous solution of the additives is added in a separate mixing operation, immediately followed by the application in situ of the finished blend. This method avoids the difficulties associated with the use of dry mixtures containing all three components. The invention includes an apparatus for mixing and immediate application of the blends as defined by the process claims.

  • Patent number: 4660985
    Abstract: An aerated cementitious composition is produced by feeding a mixture comprising cement and foaming agent to a mixing chamber open to atmosphere together with a feed of liquid. The ingredients are mixed and the wetted mixture pumped to a desired site, the capacity of pumping being greater than the feed rate of the ingredients into the mixing chamber such that air is drawn into the mixing chamber.
