Gypsum Calcination

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℃.

Gypsum Products

At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In the mills, hot gas contacts gypsum as it is ground. The gas dries and calcines the raw material and then conveys the product to a cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills.
