Process of Gypsum Ceiling Board Production Line

Calcined gypsum powder, water and various additives are automatically and separately measured and conveyed into the mixer. After well mixed into slurry and spreaded onto the gypsum board protective paper which is continuously moving forward. When going through shaping machine, the slurry is fully wrapped by upper and lower paper, pressed into well-regulated gypsum board which is brought forward as per a stable and strictly controlled speed.

After 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 pcs with fixed size by an auto-controlled knife. The individual boards are orderly arranged, turned over by PLC control system and brought into the dyer.

In the dryer, the absorbed water in the boards is evaporated away. Out from the dryer, the boards are gradually cooled down in the running process. The front sides of every two boards are folded after turnover, and the two ends are cut into boards with regular size and nice appearance by edge sawing machine. At the same time, the two ends of boards are packed by paper strips with fixed label. And finally the boards are conveyed to automatic stacking machine and stacked into well-ordered finished products.
