Calcining - also known as calcination - is a thermal treatment process that uses extremely high temperatures to change the physical and chemical properties of various solid materials, including minerals, metals, and ore. Calcining is used in a variety of industrial applications within the mineral processing, recycling, and manufacturing industries.
The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.

Continuous calcination of gypsum is provided by uniformly feeding uncalcined gypsum into the calcining batch in a kettle to a location below the surface but above the uppermost agitator, and allowing calcined gypsum to be discharged from the kettle through a discharge outlet in the wall of the kettle at the top surface of the calcining gypsum.
gypsum ratios. Their high availability, long life cycle and easy maintenance, combined with fully automatic operation reflect the latest in state-of-the-art technology. In order to minimize energy costs, the exhaust gases from the kettle process are used for the pre-drying process, so that an additional hot gas generator may not be required.
Calcining process ; Gypsum is ground subjected to temperatures of 110C to 130C to drive off part of the water of crystallization that is the amount of water needed to convert gypsum to its hemihydrate form. It is done in a vat or a kiln open to air. Dry calcination wet calcination. 7 PROCESS CONTD.. As the temperature is raised the remaining water
Calcining. a heating process that converts the solid form of gypsum into fine particle form. Exothermic heat. heat which is produced due to the chemical reaction during setting. Setting time. the measure of time from the beginning of the mix until it is completely hardened and set.

In a process called calcining, the powder is heating to approximately 350 degrees F, driving off three fourths of the chemically combined water. The calcined gypsum, or hemihydrate, becomes the base for gypsum plaster, gypsum board and other gypsum products.
At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills.
