Gypsum powder machine

1:Brief Introduction
Natural gypsum generally includes dehydrate gypsum and anhydrous gypsum.

In order to get the valuable materials, generally, we get semihydrated gypsum through heating the dehydrate gypsum.

Gypsum mine ->Breaking ->Grinding ->Calcining ->Lifting ->Conveying ->Finished products (CaSO4.1/2H2O)

3:Raw Materials
Content of CaSO4.2H2O in gypsum mine should be more than 80%
The grade of mine and the crystal configuration will influence the quality of semi-hydrated gypsum.
