Natural gypsum generally includes dihydrate gypsum and anhydrous gypsum. In order to get the valuable materials, generally, we get semi-hydrated gypsum through heating the dihydrate gypsum.

2.    Production scale

20000tons per year ~200000tons per year

3.     Main technology

Gypsum mine→ first breaking →second breaking →grinding →calcining →aging →finished products (CaSO4·1/2H2O)

4.     Raw materials

Content of CaSO4·2H2O in gypsum mine >80%.

The grade of mine and the crystal configuration will influence the quality of semi-hydrated gypsum.
