Chemical Gypsum Drying Methods and Application
Gypsum is important Additive used for Cement Production. It’s also known as Regulator. It’s contributes for strength acceleration in early stages of hydration. It also give hardness to the Cement. Following table describe Properties of Mineral Gypsum and Chemical Gypsum Which are Generally useful for Cement industry.

Gypsum is a monoclinic mineral and is a hydrate of calcium sulfate (CaSO4). Natural dihydrate gypsum (CaSO4·2H2O) is also called raw gypsum. After calcination and grinding, β-type hemihydrate gypsum (2CaSO4·H2O) can be obtained, which is architectural gypsum, also known as plaster of paris and plaster. Gypsum is a widely used industrial material and building material. It can be used for cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler, paint filler, etc. The microporous structure and heating dehydration of gypsum and its products make it excellent in sound insulation, heat insulation and fire resistance.
The heat treatment of gypsum is divided into drying and calcination. Drying is to remove surface water, and calcination is to remove crystal water.
Zhengzhou Hengyang has been designing and manufacturing gypsum drying and calcination equipment since the year 2010. So far, more than 50 sets of gypsum drying and calcination equipment have been designed and manufactured. We have cooperated with Saint-Gobain, Grenzebach, CNBM and accumulated mature technology and equipment from years of engineering experience. We can provide customers with various types of gypsum drying and calcination production lines of 50,000-300,000MT/ year.
