What Is Calcination Of Gypsum
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 120180℃....

Gypsum
Gypsum is the name given to a mineral egorized as calcium sulfate mineral, and its chemical formula is calcium sulfate dihydrate, CaSO 4 ⋅ 2H 2 O. However, a broader definition includes all the calcium sulfates, including calcium sulfate hemihydrate, CaSO 4 ⋅ 2 O, which is known as plaster or plaster of Paris (POP). Figure 6 summarizes the polymorphism of calcium sulfate; ....

The Calcination of Kaolin Clay
If the temperature is allowed to exceed 1100°C, a carcinogenic material known as cristobalite will form. Kaolin calcination is most commonly carried out in a rotary kiln, often referred to as a calciner. This thermal processing device is incredibly flexible and can be configured to meet a wide variety of processing conditions....
