Gypsum is the aquo-complex whose main component is CaSO4.It is widely used as industrial and construction material. Usually, the gypsum includes plaster stone and anhydrite. Plaster stone is Ca〔SO4〕•2H2O, also known as hydrated gypsum and soft gypsum. Its structure is compact mass and threadiness and the Moh's hardness of …
Crushing process. First, the gypsum raw material to be calcined is sent to the silo, and then sent to the calciner by the feeder for calcination. Under the action of mechanical dispersing force and hot air generated by the gas, the material undergoes processes such as dispersion, drying, calcination and strong high-speed homogenization.
By combining a bibliographic review with local visits/interviews and experimental gypsum calcinations, we were able to document traditional processing …
Natural gypsum, shown in Fig. 25.1, is the most common raw material for production of binders.It is a soft mineral, attributed to sedimentary rocks, normally grey or with no colour, with a humidity of about 8–10%. Gypseous stone, a denser modification of gypsum that is composed of gypsum and sandy and clayey stone, is normally used to …
This process leads to a gypsum by-product known as titanogypsum or also simply called red gypsum. Red gypsum waste is usually slurried with water and then pumped out of the TiO 2 pigment plant to nearby landfill site. Red gypsum contains mainly hydrated CaSO 4 (70% wt), Fe 2 O 3 (30% wt), and very small amount of Al 2 O 3 [20]. …

Introduction. Flue gas desulfurized gypsum mainly comes from thermal power plants, smelters, and large-enterprise boilers, and contains industrial by-products produced through a wet desulfurization combustion process, where SO 2 gas and lime slurry react under strong oxidation conditions. The main component of this gypsum is …

According to the U.S. Energy Information Administration's statistics, in the 2006–2016 period, approximately 42% of the electricity consumed in the U.S.A was produced by coal combustion (U.S. Energy Information Administration, 2018).The coal combustion process generates various types of residues such as fly ash, bottom ash, …
The preparation of α-calcium sulfate hemihydrate (α-HH) from industrial by-product gypsum is an important way to solve the massive accumulation. α-HH possessing larger, dense and well-grown crystals with fewer cracks and pores has high added value and a wide range of application. Hitherto the preparation methods of α-HH from industrial by ...
Gypsum-based mortars and plasters are typically made up of one volume of gypsum to two or three of sand, with enough water added to make the mix. sufficiently workable. As the mix may start to stiffen only five minutes after adding the water, it is important to make up only small quantities of plaster and to. gypsum.

The production of plaster and plasterboard puts very little pressure on the environment. The final product is non-toxic and wastage and unwanted by-products from the process are minimal. The technology uses gypsum and fuel only and its waste product is mainly gaseous water and carbon dioxide. So, the process is environmentally friendly [57].
The capabilities of gypsum as a building material depends to a great extent on the chemical composition of the raw material. To ensure targeted, high-quality processing into gypsum plaster, plasterboard or gypsum blocks, you need technology solutions that process natural or synthetic gypsum into stucco or high-fired plaster.
