Gypsum | Definition, Uses, & Facts | Britannica

Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water. For an especially hard-finish plaster, the gypsum is completely dehydrated at a high temperature, and such chemicals as alkali sulfate, alum, or borax are added. Hair or fibre and lime or clay may be added to plasters during manufacture.

Gypsum processing and use

There are five basic stages in gypsum processing: Excavation is sometimes carried out by digging out an area of ground where the gypsum is located using open-cast techniques. To reach …

How to Process Gypsum Rock into a Gypsum Board?

Ingredients: After calcining, gypsum powder has become a kind of mortar. Now you should do the following five steps: 1 Stir the modified starch, retarder, paper pulp, water and other raw materials are stirred to make raw material pulp. 2 the ing agent 3 Mix coagulant with mature gypsum powder

Gypsum Production Plant

Gypsum which is coming from pit is brought to the appropriate size with gypsum jaw crusher. The hammer crusher then moves to the kiln feed size. As a result of crushing process, the gypsum size is 0-10 mm and the crushed material is pulled into the feed silo with elevator. The steam formed in the kiln is isolated by the pipe system.

How Is Gypsum Formed? | Hunker

Gypsum is a sedimentary rock and a crystalline mineral. "Gypsum is a soft, white to gray, "chalky" mineral composed of calcium sulfate and water," says Raymond Anderson of Iowa's Department of Natural Resources. Gypsum's chemical symbol is CaSO4•2H2O. Found in many parts of the world, it ...

Gypsum Mining Method & Cost

The formation of gypsum in commercial quantities can generally be ascribed to one of three causes: Transformation of deposits, generally limestone, by chemical reactions involving weak solutions of sulfuric acid; precipitation from sea water, due primarily to concentration by evaporation; or reactions between the salts in solution.

Gypsum processing and use

Gypsum Processing and Use Practical Action 4 are more efficient than burning the gypsum in mounds or pits, and even a small kiln may use less than half of the fuel of a pit or mound. It is easiest to judge when enough heat has been applied if an indirectly heated pan or metal plate is used. When the temperature of the surface is increased steam ...


The production process of gypsum products can be broken down into four stages: exploration, quarrying, processing, panel production. The data resulted from the first process, i.e., the exploration process is used to determine the configurations of the components used in the later stages of gypsum production.

Gypsum Board production flow | YOSHINO GYPSUM

Calcined "gypsum" is mixed with water to make a slurry (muddy state). Then, the slurry is poured into a line (belt) where board liners are flowing down, thus sandwiched with board liners. Drying process Boards are sent to a drying machine (dryer) to remove excess water content. Finishing process Boards are cut into products with appropriate size.


Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard or sidewalk …

Use, Benefits and Types of Gypsum Plaster

Gypsum plaster replaces Portland cement with Gypsum as a binding substance. It is a white cementing substance formed by dehydrating Gypsum to a partial or complete degree. Dry gypsum powder hardens when water is added to it. It's ready to use and doesn't require any sand. All that's needed to get started is a little bit of water.

Understanding Gypsum

Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 O). It is a natural mineral that occurs in certain types of sedimentary rocks. Gypsum forms when water evaporates in mineral-rich marine soil environments. Over long periods of time, evaporation brings more minerals to the soil surface, eventually forming a solid deposit.

Gypsum: Types, Properties, Advantages & Disadvantages

Gypsum can be transformed into a calcium sulfate whisker in an aqueous medium under the conditions of high temperature and high pressure. Calcium sulfate whisker can be used as reinforced filler in resin matrix composites, friction materials, binders and other industries.

In all, more than 90 countries produce gypsum. In most open pit gypsum operations, benches are drilled and blasted using ammonium nitrate as the explosive. Because gypsum is so soft, most drills can drill through it at a rate of roughly 23 ft per minute. Sometimes the drill holes become wet, which can cause problems with the ammonium nitrate.

Calcining processes for natural and synthetic gypsum | Grenzebach

During the process, the phases of the CaSO 4 x H 2 O system can be optimally adjusted. Rotary kilns are used for the calcining natural gypsum. In this process, pre-crushed natural gypsum is calcined in parallel flow with the flue gas. Fine grinding mills then grind it to its final particle size. Fact-Sheet Rotary kiln (EN)
