Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.
The processof continuously calcining raw gypsum, which includes the steps of moving finely divided gypsum through an inclosed space in association with and fluidi zed by a current of steam which is at a temperature above gypsum calcining temperature, and simultaneously heating the mixture to the temperature of gypsum calcination, whereby the ...
Calcination of Gypsum was an accidental discovery as were its rehydration characteristics. Ancient man probably used lumps of Gypsum to enclose his fire. Some degree of calcination and softening occurred and when the fire was extinguished with water he noticed the lumps soon hardened.

mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco.

Jul 24, 2007· Hello; I am working in a gypsum plaster plant and I have been given a task that is related with comparing our current calcination system with our other subsidiaries' calcination systems. To compare them, I got a questionary about the system. One of the question was "what is the calcination set point". At the first glance, I thought that is the outlet temperature of the stucco.
