Bassanite Raymond mill

Gypsum has three main types: gypsum, anhydrite and architectural gypsum. The gypsum is also called dihydrate gypsum, anhydrite is also called anhydrite, and architectural gypsum is also called hemihydrate gypsum α and β Type. Natural dihydrate gypsum (CaSO4 · 2H2O) can be obtained after calcination and grinding β Type I hemihydrate gypsum (CaSO4 · 1/2H2O), namely building gypsum, also known as Bassanite. Bassanite is obtained by calcining gypsum, so what kind of pulverizer is used for bassanite pulverizing?

Recently, the bassanite pulverizing production line designed by Guilin Hongcheng for the customer was officially put into production.

Bassanite pulverizin can be divided into two processes: burning before pulverizing and pulverizing before burning. Not only in China (Hunan, Fujian, etc. in the south), but also abroad (Germany, Japan, etc.), there are two processes: burning before grinding. Both processes can produce high quality bassanite powder as long as the equipment operates properly and the design is reasonable. The customer adopted the process of burning before grinding, and chose Guilin Hongcheng HCQ1500 Raymond mill, and fineness is 200 meshes, D95. As the bassanite hardness is lower than the raw material, it has better grindability and higher output.
