Plasterboard Making Machine

Plasterboard Making Machine

A plasterboard making machine refers to the integrated line that produces drywall panels, combining raw material preparation with forming, cutting, and finishing processes.

Raw Material Preparation
Core ingredients—gypsum powder, water, and retarders—are stored in separate silos. The slurry preparation station blends these components to create a uniform mix. Chemicals that control setting time and improve board strength are added in precise quantities.

Board Forming and Pre-Setting
The prepared slurry is cast between two layers of paper supplied by unwinding units. A forming conveyor shapes the sandwich into a continuous panel. Pre-setting time on the conveyor allows the core to partially harden before cutting.

Cutting and Trimming
Cutting units downstream score and cut the board to pre-set lengths. Edge trimming stations can bevel or square the board edges, preparing them for joint treatment during installation.

Drying Section
Boards move through a multi-zone drying kiln, where staged temperature profiles gradually remove moisture without causing surface cracking. Energy-saving designs often recover heat from exhaust air to preheat incoming air streams.

Finishing Lines
After drying, optional operations include surface sanding, face paper recoating, or lamination with specialized facings (e.g., water-resistant paper). These finishing processes adapt the boards for specific environments, such as bathrooms or commercial spaces.

Automation and Monitoring
A centralized control system manages speeds, slurry feed rates, kiln temperatures, and cutting positions. Real-time data from sensors—monitoring board thickness, moisture, and line speed—ensures consistent production and early detection of deviations.

Storage and Distribution
Finished boards are stacked and banded before being moved to storage areas. Inventory management systems track board specifications and quantities, optimizing order fulfillment and reducing lead times.
