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 etc Content of CaSO4·2H2O in gypsum mine > 80%.
Gypsum board production line adopts the German GRENZEBACH BSH and GYPTECH company, Lafarge, the United States INC companies and domestic well-known enterprises Kitashinchi Group, Taihe Group advanced technology. We adopts the horizontal flow, vertical airflow heat exchanger heating system, the raw material feeding system and edge cutting and edge sealing and edge grinding and recycling system and stacking system are all controlled by computer. All the whole line is full automation. Gypsum powder production line adopts boiling furnace, high-voltage electrostatic dust removing and other advanced equipment, it is energy-saving and environmental protection. Technology introduction of boiling furnace With the development and progress of gypsum industry, the need of gypsum powder is growing, also with the quality of gypsum powder. During the whole procedure, the drying and dehydration are the key link, and it is also the difficult part. According to such a condition, after many years researching and exploring, we have developed a new generation dehydration device which are suitable for all kinds of gypsum production demand boiling furnace
The main principle of drying system: the boiling furnace body is consist of delicate and intensive cooling coil pipe. Put the heat conductive oil in the pipe, and release the heat into the inside of furnace. There is a Roots blower under the bottom of boiling furnace, and blow the air into the furnace, until blowing the powder into boiling status. Under a certain temperature, the dried and dehydrated powder become light, and flow to the outlet automatically. The quality of this kind of gypsum powder is stable, because the equipment adopts dried electrostatic dust remover, so the dust-removing efficiency is above 95%.
