Gypsum Wikipedia
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/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
Raw Materials of Gypsum Board SHANGHAI SANME
The gypsum powder production line is to calcinate natural dihydrate gypsum ore (raw gypsum) or industrial by-product gypsum (desulfurized gypsum, phosphogypsum, etc.) at a certain temperature. It is ground to make the dihydrate gypsum dehydrated and decomposed. The product with β hemihydrate gypsum as the main component is the building gypsum (commonly known as plaster of gypsum).
