Modern Gypsum Board Production Line: Intelligent, Efficient, and Precise Technical Core

2026-06-05

1. Intelligent Automation Control: SCADA System Drives Full Process

The modern gypsum board production line is centered around a Supervisory Control and Data Acquisition (SCADA) system, enabling full-process automation control across the entire plant. The SCADA system not only monitors equipment operation and process parameters in real-time but also performs automatic adjustments through intelligent algorithms, significantly reducing manual intervention and ensuring production continuity and stability.

Key automation features include:

•Paper Counter: Accurately tracks paper consumption, optimizing material management.

•Forming Table Vibrator: SCADA automatically controls lifting/lowering to ensure uniform slurry spreading, enhancing board density.

•Dryer Temperature/Airflow Regulation: SCADA precisely controls thermic oil flow (via automatic valves) or partitioned airflow (for hot air systems) based on set temperatures, ensuring uniform drying and energy efficiency.

•Forming Belt Auto Alignment System: Automatically activates when the belt deviates beyond a threshold, preventing misalignment and ensuring production continuity and stable product dimensions.

2. Precise Material Preparation: Quality from the Source

Material preparation is the foundation of gypsum board quality. Modern production lines emphasize efficiency and precision in this stage.

Core technical highlights:

•New HRA (BMA) Ball Mill: Provides higher grinding efficiency and more stable calcined gypsum powder quality.

•Beltway Feeder (BWF): Features an enclosed/covered structure to prevent dust accumulation from affecting metering accuracy, ensuring precise additive feeding.

•Calcined Gypsum Silos: Four silos, each with 60-70 MT capacity, ensure material supply for 24/7 continuous production.

•Dry/Wet Additive Feeding Areas: Well-organized for minimal labor and intelligent operation, improving feeding accuracy and efficiency.

3. Efficient Precision Forming: Shaping Superior Boards

The forming process directly determines the physical properties and aesthetic quality of gypsum board. Advanced technologies are employed to ensure precise shaping.

Main technical configurations:

•Paper Unwinding Unit and Auto Splicing Unit: Ensure continuous and stable supply of top and bottom facing paper, reducing downtime.

•New Technology Mixer: Optimized design for fast and uniform mixing of gypsum slurry, ensuring stability for subsequent forming.

•Advanced Scoring Unit: Prioritizes bladeless, motorized, or purely mechanical male/female disc mechanisms, providing more precise and smoother board edge scoring, reducing maintenance costs.

•Standard Extruder: Adjustable top and bottom plates for precise thickness adjustment, ensuring board thickness meets standards; pneumatic cylinders require zero maintenance.

4. Optimized Drying and Quality Assurance: Achieving Final Performance

Drying is a critical energy-consuming stage in gypsum board production, with profound impacts on the final product quality.

Drying system optimizations:

•Dryer Inlet Auto Knife Blade: Top and bottom blades are adjustable for cutting depth, ensuring equal load; includes an auto sample board cutting mechanism (1-meter length) for quality inspection.

•Dryer Inlet New Conveying Equipment: Replaces star screws with low-maintenance new conveying equipment, enhancing equipment reliability.

•Taper Edge Cooling System: Standard feature in the dryer, effectively mitigating stress concentration and cracking caused by rapid drying at board edges, ensuring board flatness and strength.

From intelligent central control to material preparation, forming, and drying, the optimization of every stage aims to enhance overall operational efficiency; the future of plasterboard production will continue to evolve toward greater integration, intelligence, and environmental sustainability.
