摘要
An improved process for producing calcined gypsum which comprises continuously treating a mass of calcined gypsum by adding, with thorough blending agitation, small metered portions of water to result in the incorporation of about 1-8% free water in the mass by weight of the gypsum, allowing the blended mass to heal the calcium sulfate hemihydrate surface fissures and thereafter continuously supplying the treated gypsum mass into gypsum board production.
