How drywall is made material, manufacture, making, used The primary component of drywall is the mineral gypsum. It is a lightdensity rock found in plentiful deposits worldwide. Each molecule of gypsum (or dihydrous calcium sulfate) is composed of two molecules of water (H 2 0) and one of calcium sulfate (CaSO 4 ). By weight the compound is 21% water, but by volume it is nearly 50% water.Gypsum Processing feeco.comGypsum can be a difficult material to process, from its variability, to its tendency to harden into a cementlike form, and its abrasive nature. For this reason, choosing processing solutions that are heavyduty and designed around the unique characteristics of the gypsum sample
Innovative gypsum processing at GIPS AD Global GypsumThe gypsum calcining systems are designed to process natural gypsum from the local underground gypsum quarries. A greenfield project To take over production from the old three calcining kettles, the new calcining line was designed for a plaster capacity of 14t/hr, utilising a Claudius Peters EM 47568 Gypsum Calcining Mill.Recycling Process New West GypsumRecycling Process. New West Gypsum Recycling receives preand postconsumer gypsum waste, reconstitutes the materials into useful products and provides the raw material for new manufacturing. Our successful business model incorporates agreements with wallboard manufacturers that secure a strong supply and demand for the gypsum material.
Cement & gypsum Schenck ProcessUses of two elementary building materials: gypsum and cement production. Cement is used everywhere imaginable: for example, as a binder for concrete, mortar or screed, making it one of the world's most important building materials.

Benefit from our wide range of cement and gypsum products.What is Gypsum? Gypsum AssociationGypsum rock is mined or quarried, crushed and ground into a fine powder. 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.
Gypsum recycling WikipediaGypsum recycling process. Gypsum waste can be turned into recycled gypsum by processing the gypsum waste in such a way that the contaminants are removed and the paper facing of the plasterboard is separated from the gypsum core through mechanical processes including grinding and sieving in specialised equipment.
