  • Mixer for foamed gypsum products
    Patent number: 6742922
    Abstract: Apparatus for mixing aqueous foam with a slurry of gypsum and water. A cylindrical housing includes, in its upper end, an inlet for a slurry and a helical diverter for directing the slurry in a downward spiral flow path. An inlet for aqueous foam in located in said diverted and directs the foam into the incoming slurry. An annular flow restrictor is located in the lower end of the housing. Turbulence resulting from diversion of the incoming slurry from linear flow to a downward spiral flow path and from changes in spin diameter and speed through the flow restrictor uniformly mix foam with the slurry.
    Type: Grant
