Manufacturing Process of Gypsum Board
1. Material batching
Raw gypsum should be grinded into fine pulver and calcined first. Then, certain amount of water and additives are added into the semihydrate gypsum and the mixture is conveyed to a pin mixer in the front of the board forming line. The additives include starch, accelerant, forming agent, and so on.
2. Board moulding
The slurry produced in the pin mixer is conveyed and spread between two paper sheets that serve as a mould. The edge of the paper sheets can be scored and chamfered according to specific requirement to form the edges of the board.
3. Board drying
Since the board delivered out from the moulding section is wet, it should be conveyed to a dryer. When the gypsum board is on the conveying line, the calcium sulfate hemihydrate combines with the water in the slurry to recrystallize and rehydrate, reverting to its original rock state to give a rigid board. The board is then sent to a multilayer kiln dryer and is dried by direct contact with hot combustion gases or by indirect steam heating to remove any free moisture.
4. Sawing and trimming
The dried board is then conveyed to the board end sawing area where it is trimmed and bundled for easy delivery.
