摘要： An apparatus and method for introducing a metered volume of air into a continuously generated and flowing slurry composed of metered dry cementitious material, metered water and metered air entraining (or foaming) agent and for homogenizing this air into bubbles or cells of relatively small size to produce a uniform cellular product. The apparatus comprises a positive displacement progressive cavity slurry pump driven by a variable speed motor. By driving the pump at a speed in excess of the speed required to accommodate the volume of slurry being generated, the pump will draw air proportionately to this excess of speed. Further elements of the apparatus comprise a closed conduit system for the slurry discharging from the pump, this system communicating with a cylindrical homogenizing apparatus wherein rotating elements homogenize the metered air and slurry with the cooperation of the air entraining agent into a foamed material having relatively small air cells of uniform size. The homogenized slurry material is propelled through and beyond the homogenizing apparatus through a communicating conduit to the point of deposit.

摘要： An apparatus and method for producing a slurry of dry metered plaster and metered water on a continuous basis. The apparatus consists of an element functioning to receive dry metered plaster and to agitate this plaster before discharging it downward from a discharge aperture. An additional device receives metered water and causes it to eject in such manner as to surround and encompass the discharging dry plaster in sheets or sprays of water. A receptacle element is disposed to receive the plaster and water and is so configured that the commingling mixture will descend along the side of the receptacle into an aperture at the base. Additionally a progressive cavity pump is disposed in juxtaposition and communicating with the receptacle aperture so that the commingling mixture will draw into the pump. Upon passing through the pump the mixture is transformed into a homogeneous slurry and is propelled through a conduit to the point of use.
