Natural gypsum (CaSO4 • 2H2O), also known as gypsum, could be processed into β-hemihydrate gypsum (CaSO4 • 1 / 2H2O) by calcining and grinding, namely building gypsum, plaster or stucco. If the calcination temperature is 190 ° C, we can obtain model gypsum, whose fineness and whiteness is higher than construction gypsum. If natural gypsum is calcined under 400-500 ° C or above 800 ° C temperature, the final material would be flooring gypsum, which clotting, hardening are slow, but the strength, abrasion resistance and water resistance after hardening is better, compared with ordinary building gypsum. Usually selenite is white, colorless or transparent crystal, sometimes due to impurities and ash, the appearance could be yellow, light brown and other colors.

Gypsum Processing Plant

1.The large size crusher gypsum ore is broken into less than 30mm granule by crushers. Then be delivered to the grinding mill;

2.Gypsum powder production line adopts Chinese domestic mature and advanced process and equipments, such as vertical mill and boiling furnace etc;

3.The qualified gypsum powder, which reaches required fineness, could pass separator and is transported into boiling furnace by air to be calcined. The rest big powder would return mill again. Boiling furnace is the most widely used equipment in china in building gypsum process industry. The virtue is its simple structure and easy operation;

4.Calcined gypsum powder would be stored by silo or packed by bags for sale, or transported into following workshop directly;
