Abstract: An agitation mechanism for a gypsum processing apparatus which includes a housing (12) having a top wall, a bottom wall, and at least one side wall. The housing can be constructed and arranged to receive and process gypsum-based products. An agitator frame (64) having a similarly shaped cross-section to the cross-section of the housing is provided and positioned adjacent the bottom wall (55) of the housing. The agitator frame (64)is pivotally connected (68, 70, 72) internally to the housing for reciprocating movement between first and second positions. The agitation mechanism is operable (74) for preventing fluid channeling to ensure good fluidization of the gypsum products from collecting adjacent the bottom wall of the housing.

Abstract: The present invention is an apparatus and process for cooling and de-steaming hot calcined stucco used in the production of gypsum boards or bagged plaster. The apparatus is a fluid bed stucco cooler and comprises a cooler housing having a plenum having a stucco inlet and stucco outlet. The stucco cooler includes a rotating disk in the plenum. The rotating disk includes nozzle for spraying fluid, and is attached to a rotable shaft extending from the side of the cooler also includes a fluidization pad and agitator to help to mix the air and the stucco powder to insure fluidization, prevent channeling, and prevent the stucco powder from building up on the various components. The air also forces steam from the hot calcined stucco out through an air outlet located at the top of the stucco cooler, thereby de-steaming the stucco. The stucco flows through the plenum and passes over the cooling coils, thereby cooling the stucco as it reaches the stucco outlet.

Abstract: An apparatus for calcining gypsum including a housing having a bottom wall, opentop, and a plurality of side walls extending therebetween. A fixture is located adjacent the open top for receiving gypsum from a source and transferring the gypsum into the housing. At least one burner is connected to the housing and operable for combusting an air-fuel mixture to heat the gypsum. At least one serpentine burner conduit extends from the burner through the housing and terminates through a support floor of the apparatus. The exhaust flow is then directed through a fluidization pad and into the gypsum to further heat the gypsum product. An agitation mechanism is operable to mix the gypsum adjacent the fluidization pad to prevent pockets of gypsum from coagulating and preventing fluidization of the gypsum.
