gypsum powder processing line

1.fully automatic 
2.natural gypsum
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 powder production line adopts boiling furnace, high-voltage electrostatic dust removing and other advanced equipment.
