APPARATUS AND METHOD FOR TREATING GYPSUM
[Object] The object of the present invention is to provide a fluidized-bed-type apparatus and method for treating gypsum, which can activate or improve fluidity of gypsum powder to promote an effect of treatment of gypsum, such as modification or homogenization of the gypsum powder.[Solution] The apparatus for treating gypsum (1) comprises a reactor vessel (2), a conditioned air supply port (6), a horizontal partition wall (5) and a plurality of stationary vanes (10). The wall allows a conditioned air flow (Af) to flow upward into a reaction region (α). The vanes are arranged at an angular interval in a circumferential direction. A fluidized bed (M) of calcined gypsum (Gb) is provided in the vessel. The vane deflects the conditioned air flow (Ag) flowing upward into the reaction region, toward a radially outward and circumferential direction of the reaction region. The calcined gypsum (Gb) makes a saltational fluid motion or saltational movement in the vessel with the air flow.
