The invention discloses a calcining process of gypsum. The calcining process includes the steps of taking plaster of paris as a binder, adding coal dust with a particle size smaller than 0.2mm and water, mixing the mixture into sticky coal paste, adding gypsum ore particles with a particle size of 5-10mm into the coal paste with stirring to enable the …

Calcination also known as calcining is a process of heating a solid compound at a very high temperature below its melting point. This process is carried out in the absence of oxygen or a limited supply of oxygen. The process involves heating a substance to high temperatures, typically between 700 ℃ to 1200 ℃, although the …

Rotary kiln. Calcination in a rotary kiln is a direct, long-time 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, pre-crushed natural gypsum is calcined in parallel flow with the flue gas.
