11.16 Gypsum Manufacturing - US EPA

11.16 Gypsum Manufacturing 11.16.1 Process Description1-2 Gypsum is calcium sulfate dihydrate (CaSO4 2H2O), a white or gray naturally occurring mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters orHow Gypsum is Made - AWCI,of the manufacturing process. The stucco is blended with water and other ingredients (depending on the type of wallboard being made) to make a “slurry,” or paste. This stucco slurry will then be spread onto paper to form wallboard. The “Bread” That Makes the Wall-board Gypsum wallboard is frequently described as a “sandwich,” with gyp-Generic Gypsum - NIST,The gypsum is fed into a mixer where it is combined with water and other ingredients to form a slurry or paste. The slurry is spread on a moving belt of face paper and then covered with a backing paper. As the to,Emissions from Gypsum Board Manufacturing .

Stucco is manufactured from natural rock or from a synthetic source by: Drying The crude gypsum rock is put through a kiln to remove excess water that was common from the sourceGypsum - Wikipedia,Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall. A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval EnglandMethod and Apparatus for Manufacturing Gypsum,- Justia,When, as is commonly the case, the additives and other ingredients are required within the gypsum product manufacturing process, these may be added at any stage through specially provided inlets.
