Calcining processes for natural and synthetic gypsum
Calcination in a rotary kiln is a direct, longtime calcining process During the process, the phases of the CaSO 4 x H 2 O system can be optimally adjusted Rotary kilns are used for the calcining natural gypsum In this process, precrushed natural gypsum is calcined in parallel flow with the flue gasThe rate of production of gypsum plaster by a continuous calcination process, in which a mass of gypsum being calcined is maintained in a fluidized condition predominantly by the water vapour evolved during calcination, can be considerably increased and a plaster product of reduced water demand be obtained by introducing an aridizing agent such as calcium chloride along with the gypsum and controlling the Calcination of gypsum BPB INDUSTRIES LIMITED Flue gas desulfurization (FGD) gypsum is an industrial byproduct in coalfired power plants It is mainly composed of calcium sulfate dihydrate and minor amounts of impurities, such as sodium sulfate, potassium sulfate, magnesium sulfate, and chloride The gross product of FGD gypsum has reached 550 million tons in China by 2016Calcination of calcium sulphoaluminate cement using
