The main purpose of the project was to replace the main kettle (no. 1) with a continuous conical kettle. The kettle converts Gypsum to stucco via a process called calcination. The kettle and all associated auxiliary equipment will be replaced to upgrade the production from a batch to a continuous process.
To produce gypsum board, the calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of paper on a board machine. As the board moves down a conveyer line, the calcium sulfate recrystallizes or rehydrates, chemically combining with the water that was removed during calcination and reverts to its ...

The rate of production of gypsum plaster by a continuous calcination process, in which a mass of gypsum being calcined is maintained in a fluidized condition predominantly by the water vapour evolved during calcination, can be considerably increased and a plaster product of reduced water demand be obtained by introducing an aridizing agent such as calcium chloride along with the gypsum and ...
The calcined gypsum (or hemihydrate) becomes the base for gypsum plaster, gypsum board and other gypsum products. To produce gypsum board, the calcined gypsum is mixed with water and additives to form a slurry that is fed between continuous layers of paper on a board machine.
calciners may be operated in either batch or continuous mode. In flash calciners, the gypsum is directly contacted with hot gases, and the stucco product is collected at the bottom of the calciner. 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.
between the grinding rings. In continuous operation, a material bed forms between these balls and the grinding ring but when the mill The Claudius Peters EM Mill is the preferred grinding and calcining technology for the production of finished products such as gypsum wallboard. 4 calcining & grinding
Aug 05, 1975· The present invention relates to the calcination of gypsum, and more especially to a process of continuous calcination in a vessel whose contents are maintained in a fluidized state by the vapour evolved during calcination, as described and claimed in our British Pat. No. 1,018,464.

3. Rotary Gypsum Calciner Application : Rotary gypsum calciner is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. 3) The rotary gypsum calciner head adopts housing type sealing and kiln rear uses axial contact sealing unit so that reliability of sealing could be ensured.
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.
Abstract: In a process for the continuous conditioning of gypsum plaster, the gypsum plaster is passed from a calcination facility connected upstream to a gypsum plaster cooler in the form of particles. In the gypsum plaster cooler, soluble calcium sulphate anhydrite is initially converted to calcium sulphate hemi-hydrate and calcium sulphate ...
The greatest use of gypsum is in the production of plaster (calcium sulphate hemihydrate) for use as an interior finisher. Plaster is produced by the calcination (thermal decomposition) of gypsum. The most popular design is a continuous calciner where gypsum is …
