Building gypsum is a powdered cementitious material obtained by dehydration of natural mineral gypsum or industrial by-product gypsum, with calcium sulfate hemihydrate (CaSO4·½H2O) as the main component. According to the types of raw materials, it is mainly divided into: natural building gypsum, desulfurized building gypsum and phosphorus building gypsum.

Building gypsum can be made into cooked gypsum powder through the gypsum powder production line, which is the main raw material for making gypsum board.

Natural gypsum ore


Gypsum powder is the main raw material for gypsum board production. If you buy gypsum powder, each batch needs to be tested before being put into production. Otherwise, there will be problems with the quality of gypsum board, which will cause cost waste and it is difficult to find out the reasons.Therefore, the factory will have its own gypsum powder testing laboratory.

If the raw material is natural gypsum ore, it is necessary to detect the composition of gypsum ore to confirm whether it meets the standard of gypsum board raw materials, and then build a gypsum powder production line to make natural gypsum stone into gypsum powder.
