The gypsum board manufacturing process can be divided into 5 steps: raw material preparation & spraying, forming, drying, cutting & sealing, stacking & packing.
STEP 1: Raw Material Preparing & Spraying
Gypsum powder, water, and additives are fed into the mixer through the automatic metering system and conveying system to form gypsum slurry. The gypsum slurry is sprayed on the surface of the continuously moving bottom paper through nozzles. With constant movement and vibration, the gypsum slurry on the bottom paper gradually spreads evenly.
STEP 2: Forming
The bottom paper covered with gypsum slurry enters the forming machine with the moving conveyor belt, squeezed and sealed together with the top paper. After a series of high-strength extrusion and molding, the pulpous wet gypsum board is finally formed.

STEP 3: Drying
Wet gypsum board enters the dryer with the help of a transverse conveyor and the plate-turning machine. Hot air at different temperatures in the dryer evaporates the moisture from the gypsum board. As the water evaporates, the gypsum and paper stick together firmly.
STEP 4: Cutting & Sealing
After drying, the fully dried gypsum board is cut into a certain size and sealed on the edge to satisfy the customer's requirement.
STEP 5: Stacking & Packing
Finally, the processed gypsum boards are stacked and packed by stackers and packers. Then they can be transported to the warehouse by forklift.
