The natural gypsum powder includes anhydrous gypsum and CaS04.2H2O, if you want to commercialize the gypsum powder, you should adopt the CaS04.2H2O, after removing part of water by heating, it will become CaS04.1/2 H20. CaS04.1/2 H20 is the final product which you can use it to produce gypsum board other gypsum product. After calcining, CaSO4.1/2H2O is widely used in paper faced gypsum board and gypsum block and painting gypsum powder and model.Natural gypsum generally includes dehydrate gypsum and anhydrous gypsum. In order to get the valuable materials, generally, we get semi-hydrated gypsum through heating the dehydrate gypsum.
The calcined semi-hydrated gypsum can widely be used for plasterboard, decoration board, gypsum block, stucco gypsum, and molding gypsum etcContent of CaSO4·2H2O in gypsum mine > 80%. The grade of mine and the crystal configuration will influence the quality of semi-hydrated gypsum
The Crusher will break the big-size gypsum ore into small 25mm pieces, and then the small pieces will ne sent to the grinder, after grinding fine, the qualified raw gypsum powder will be sent to boiling furnace to calcine, and the unqualified part will be sent to grinder until it’s qualified. After calcining, the qualified gypsum powder will be sent to storage or workshop.
