Production Method of Gypsum Board Production Line:
This production line used  the  calcined gypsum powder, water and various additives are automatically and separately measured and conveyed into the mixer by continuous auto-conveying system. After well mixed into slurry and spreaded onto the gypsum board protective paper which is continuously moving forward. During the progressing process, the slurry is gradually dispersed with vibration, and jointed with back protective paper.  When going through extruded shaping machine, the slurry is fully wrapped by upper and lower paper, pressing into well-regulated flat board which is continuously brought forward as per a stable and strictly controlled speed. After any minutes , the calcined gypsum in the slurry is hydrated again and crystallized into tiny interpenetrative dihydrate gypsum crystal with higher strength. And then, the wet gypsum board with a certain strength and regular shape is precisely cut into individual boards with set size by an auto-controlled cutting system. The individual boards are orderly arranged, turned over by program control system and brought into the dyer. In the dryer, the absorbed water in the boards is evaporated away. following strict drying system(The crystal water in the gypsum crystal has no loss). After brought out from the dryer, the boards are gradually cooled down in the running process. The front sides of every two boards are folded after turned over again, and the two ends are cut into boards with regular size and nice appearance by end sawing machine.  And finally the boards are conveyed to automatic stacking machine and stacked into well-ordered finished products before put into storage.
