First, we take certain amount of hemi hydrate gypsum powder, water and other additives. Through the automatic measurement device and automatic conveying system.

They will be conveyed into the mixer and changed into the gypsum slurry which will be scattered on continuous moving faced paper evenly.

Second, at the same time, with the continuous moving and vibrating, the slurry will gradually diffuse and even scattered, then the slurry will go into the forming machine and compound with the top and bottom faced paper.

Third, in the forming line, the wet solid paper faced gypsum board will be gradually formed after the process of recondition, natural coagulating, automatic cutting, and etc.the wet board will be arranged according to the programmed control system. With the help of the rollers, belt conveyer and overturn, they will quickly enter into the dryer.

Forth, the board will be strictly controlled in the separate temperature zone of the dryer, after blowing into different thermal hot air, and the moisture of the wet board will be evaporated. because of the reaction of the starch,, the board will be attached to the faced paper, and then the dry gypsum board will form and exit from the dryer.moreover, after passing though overturn and the folding device (the front side is inside) for the second time, the board will be cut into certain specification by saw.

Finally, the finished gypsum board will be conveyed to the automatic sealing device and the stacker. After the stacking, the board will be transported to the finished products warehouse by the forklift.
