Presented at Global Gypsum Conference 2016 by Robert Morrow. Building a gypsum board factory can be complicated! There are many decisions to make regarding the location of the plant, the conditions and expectations in the local market, the size, layout and scalability of the plant, the technology of the equipment (calciner, mixing, dryer), the options for equipment suppliers, .
The ground gypsum leaves the mill and is conveyed to a dust collector. Calcining. Plaster or stucco is made by calcining the raw gypsum to convert the dihydrate into a hemihydrate, and is known as calcined gypsum. In some plants, landplaster is fed to kettle or flash calciners to produce plaster. Calcining occurs at about 250°300°.
CertainTeed mines and processes gypsum rock (CaSO 4•2 H 2O) to produce gypsum wallboard. The gypsum is calcined to produce stucco (CaSO 4•1/2 H 2O) in the manufacturing process. Stucco is the principal component in gypsum wallboard. Mining is covered by NAICS Code 212399 and all other processes are covered by NAICS Code 327420.
Plant Support Process and Cost Optimization; 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 ...

Rotary Calciners. Rotary calciners, also commonly called indirect kilns, are used in various calcination operations where exhaust gases must be minimized, when processing finely divided solids, or where temperature must be tightly controlled along the length of the kiln.. A calciner is comprised of a rotating drum inside a furnace, which is externally heated.

The flash calciner unit forms the heart of an entire calcination plant. As with our flash calciner, modular design is a defining feature of such a calcination plant. The plant setup covers several stages leading up to calcination, including predrying, pulverising and a controlled feed system.
A precalciner cement plant in Guizhou Province in Southwest China was selected to investigate the mass dependent fractionation (MDF) and mass independent fractionation (MIF) of Hg in the entire production process and the speciated Hg isotope composition in stack gas. Significant MDF and insignificant MIF were observed in this cement plant.
gypsum is taken directly and continuously from the calciner at full calcining temperature and introduced into the homogenizer. The homogenizer consists of a vertical reactor, where the reactor floor is covered by a fabric allowing even distribution of the fluidization gas. The gypsum bed then floats freely in .
Gypsum is a material that is calcined at a relatively low temperature (150°C 180°C). To produce high quality plaster, continuous control of the process is essential. The Rapidflow calciner is fully automated and assures complete control over the process at all times.
Q: What is the process involved in flash calcination? TK: For customers dealing specifically with fine ores, we designed the Gas Suspension Calciner (GSC) technology – something we have supplied since the beginning of the 1970s. It consists of a series of preheating cyclones, a calciner vessel and a series of cooling cyclones.
calciner design. Where other fuels or waste heat streams are to be used the calciner readily adapts to indirect firing. The calciner can also be adapted to utilise wasteheat recoverd from the calciner exhaust stream. The adoption of this feature will naturally reduce the plant operating costs and the total energy embodied in the end product.
Khatib, in Sustainability of Construction Materials (Second Edition), 2016. Chapter 25 concludes that, because of an increase in demand, gypsum mining will also increase. However, demand will force the construction industry to use more synthetic, waste and recycled gypsum. In Europe, it is anticipated that by 2035, 25% of recycled gypsum will be used.
