[Object] Fluidization of a deposit of raw gypsum in a calciner is so improved as to prevent uneven calcination of calcined gypsum from occurring and reduce a fuel consumption of the calciner. [Solution] An apparatus for calcination of gypsum includes a gypsum calciner (1, 3-7) having an interior wall surface with a circular or annular configuration as seen in its plan view, and a tubular ...
When cooling the hot gypsum is fed in counter-flow to the cooling gas. Indirect cooling then makes it possible to use the cooling gas as preheated combustion air, which in turn leads to a reduction in the thermal energy required by the calciner. The outlet temperature of the gypsum can be kept constant by means of a controlled

In a flash calciner, gypsum is in direct contact with hot gases. At the bottom of the calciner, gypsum is accumulated. Heat treatment is conducted at temperatures of over 500°C. Calciners provide complete recirculation of exhaust gases, which enables efficient fuel performance (Fig. 25.9).
Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction.These treatments can be applied to powders, granulates, suspensions and green bodies.A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.
