    • A method for continuously forming gypsum-based panels of high fixing strength comprises the steps of: • forming a mixture comprising stucco, non-pregelatinized migratory starch, glass fibre, fluidizer and water; • casting the mixture in a continuous band; • maintaining the band under conditions sufficient for the stucco to form an interlocking matrix of set gypsum; • cutting the band to form one or more wet panel precursors; and • drying the wet panel precursor to form one or more gypsum-based panels. • The weight ratio of water to stucco in the mixture is less than 0.7; • the stucco is present in the mixture in an amount of over 60 wt% relative to the total solids content of the mixture; • the starch is present in the mixture in an amount of over 3 wt% relative to the the stucco; • the glass fibre is present in the mixture in an amount of over 1 wt% relative to the stucco; • the fluidizer is is present in the mixture in an amount of at least 0,1 wt% relative to the stucco; and the density of the gypsum-based panel is greater than 700 kg/m.

    • 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.
