Gypsum Board Production Process
Gypsum board, commonly known as drywall or plasterboard, is a widely used building material for interior walls and ceilings. Here’s how it’s manufactured:
Raw Materials Processing:
Gypsum powder, water, and other additives are carefully measured and mixed in an automated system.
The mixture enters a mixer through a conveying system.
Calcination Process:
Raw gypsum is baked in a furnace, transforming it into “calcined plaster.”
Calcined plaster solidifies when it reacts with water.
Molding Process:
The calcined gypsum is mixed with water to create a slurry (a muddy state).
This slurry is poured onto a moving belt where board liners flow down, sandwiching the slurry.
As it moves along the production line, the slurry solidifies between the board liners.
Drying Process:
The formed boards are sent to a drying machine (dryer) to remove excess water content.
Finishing Process:
Once dry, the boards are cut into the desired sizes.
Shipping and Delivery:
The finished gypsum boards are loaded onto trucks and delivered to various locations.
