Gypsum Board Production Machinery

Precision Engineered: The 10 Million m²/yr Gypsum Board Production Line

Introduction: Defining Modern Plasterboard Manufacturing

In the competitive landscape of modern construction materials, efficiency, precision, and reliability are the cornerstones of a profitable operation. We present a fully integrated, high-performance Gypsum Board Production Line, engineered to meet the exacting standard of an annual output of 10 million square meters, based on the predominant 9.5mm thickness and 1200mm board width specification. This line is not merely a collection of machines; it is a synchronized industrial ecosystem designed for maximum yield, consistent quality, and intelligent operation, providing a definitive competitive edge in the paper-faced plasterboard market.

Core Design Philosophy: Synchronized Precision at Scale

The line is architected around a core design speed of 20 meters per minute, with a peak operational capacity of 22 m/min. This calibrated speed ensures the system reliably meets its 10 million m² annual target while incorporating a 10% performance buffer for demand surges or operational optimization. Every subsystem, from raw material handling to finished board stacking, is engineered to harmonize with this pace, ensuring seamless material flow and eliminating bottlenecks that compromise output or quality.

I. The Heart of Consistency: The Precision Batching Station

Quality begins with precision. Our batching station is the nerve center for raw material accuracy, built as a self-contained, 15m-span workshop to ensure a controlled environment. It features a complete suite of subsystems:

• Dry Systems: A dedicated gypsum powder handling circuit with a precision belt feeder (utilizing renowned brands like Chengde Chengxin) and a return system for optimal material management. A 2-ton overhead crane with 15m track span facilitates bulk material handling across the entire station.

• Wet & Additive Systems: Integrated slurry, foam generation (featuring homogenizer pumps), starch, accelerator, and wet additive systems—all with precise metering. Key components like screw pumps are selected from top-tier manufacturers such as German Netzsch to guarantee durability and dosing accuracy.

• Infrastructure: Wet additive tanks (304 Stainless Steel) and dual 22m³ process water tanks with interconnecting pumps are strategically positioned. A centralized bag filter dust collector, installed externally, maintains a clean and safe working environment by capturing dust from key points like the mixer.

II. Forming, Conveying & Cutting: The Shaping Phase

This phase transforms the homogenous slurry into a precisely formed, continuous board.

• Forming Section: Equipped with automatic paper splicing and RE-type automatic edge guiding devices for uninterrupted, aligned paper feed. The lower paper line includes a scoring device and a strategically reserved 1.5m section for optional QR code roller printing. All guide rollers are precision-engineered aluminum (G2.5 dynamic balance, HV300 hardness, oxide-coated) with minimal run-out (0.1mm).

• Forming & Conveying: A plate-type forming station consolidates the precise slurry flow with the upper and lower facing papers onto a variable-frequency drive (VFD) forming belt. A series of conveying rollers then gently transport the continuous board.

• Servo Cut-off System: A high-speed, servo-driven cutting unit performs accurate length cuts from 2400mm to 6000mm. An acceleration conveyor then transfers the cut boards.

III. Board Handling & Drying: Intelligent Logistics for Curing

Efficient handling protects board integrity before and during the critical drying stage.

• 1# Transfer & Flipping Section: This area features transverse feed rollers, a board turner, and conveying systems (1# & 2# belts). The board turner is crucial, flipping each sheet to ensure the finished face is protected during drying and that the board edges bond correctly.

• Kiln Feeding & Drying System: A distributor and feed accelerator carefully and sequentially load boards onto multiple tiers within the drying chamber. The multi-zone drying system, with its integrated heat exchangers, fan arrays, and humidity control, uniformly reduces moisture to a precise 2-3% final content. The entire drying process is managed for optimal thermal efficiency and board property development.

IV. Finishing, Stacking & Dispatch: Delivering a Market-Ready Product

The final stages prepare the board for packaging and shipment.

• Unloading & 2# Transfer: An automated unloader with PLC control and sensor guidance discharges boards from the dryer in sequence onto the 2# transfer section.

• Finishing Section: This includes a board combiner (pairing boards face-to-face), an edge squaring system, and a high-speed trimming saw to cut boards to final width. A specialized edge banding machine then seals the board ends.

• Automated Stacking & Packaging ("Three-Control" Section): A fully automated stacker with a hydraulic lifting platform, served by two stacking stations, creates neat, stable bundles ready for strapping and dispatch. A dedicated external bag filter manages dust from trimming and processing.

V. Comprehensive Project Support & Intelligent Design

We provide more than equipment; we deliver a complete production solution.

• Integrated Design: We supply overall process layout drawings, foundation design data, and detailed specifications for all utility (water, air, electricity) hook-up points, aligning with your plant's structural grid.

• Smart Layout: The line includes strategically placed service bridges and underground walkways for operator safety and accessibility at key locations: the 1# belt, 2# belt, secondary control station, and near the edge bander.

• Complete Documentation: Detailed equipment power load lists, total weight breakdowns, and comprehensive packaging, shipping container dimensions, and quantity information are provided for seamless logistics and installation planning.
