Main Production Equipment
1. Raw Material Preparation Section
Chipper: Converts logs, branches, and other raw materials into wood chips.
Ring Flaker: Processes wood chips into flat flakes that meet process specifications.
Screening Equipment: Removes oversized, undersized materials, and dust to ensure uniform flake geometry.
2. Drying & Classification Section
Continuous Dryer: Typically a drum or single-pass dryer, precisely controls the moisture content of flakes to 3%–5% using hot air.
Screener: Separates dried flakes into surface layer material and core layer material for gluing and forming.
Air Classifier: Further removes light impurities (e.g., dust, bark) to improve flake quality.
3. Gluing & Blending Section
High-Precision Gluing System: Includes adhesive storage, metering, and mixing units, achieving accurate glue application via online flow control.
Continuous Blender: Typically a ring or continuous blender that uniformly mixes adhesive with flakes, with separate blending lines for surface and core layers.
4. Forming & Pre-Pressing Section
Multi-Layer or Airflow Former: Lays surface and core materials evenly and in layers onto a conveyor belt to form a continuous mat.
Pre-Press: Continuously compresses the mat to expel air and enhance its strength and stability.
5. Hot Pressing Section
Continuous Press: The core equipment of the line. Uses heat and high pressure to cure the adhesive within the mat, forming a continuous board. Features a robust frame structure, thermal oil or steam heating, and closed-loop control of pressure and temperature.
6. Post-Treatment Section
Cooling Carousel: Naturally cools the high-temperature boards exiting the press to relieve internal stresses.
Trimming Saw: Cuts the four sides of the board to precise width and length.
Stacker: Automatically stacks finished boards for storage or further processing.
7. Sanding & Storage Section (Optional)
Wide Belt Sander: Calibrates the board thickness and ensures surface smoothness.
Automated Storage System: Enables automatic sorting, packaging, and storage of finished panels.
Production Process Flow
1. Raw Material Preparation
Logs, branches, and wood residues are processed through chipping, flaking, and screening to produce qualified wet flakes.
2. Drying & Classification
Wet flakes are fed into the dryer to reduce moisture content. After drying, the flakes are separated into surface and core materials by a screener. Unqualified materials are returned for reprocessing.
3. Gluing & Blending
Surface and core materials are directed to their respective blending systems, where they are thoroughly mixed with adhesives and additives to ensure bond strength and board properties.
4. Forming & Pre-Pressing
The glued flakes are formed by the former into a continuous, uniform mat on a belt conveyor. The mat then passes through a pre-press to be compacted, increasing its strength.
5. Continuous Hot Pressing
The mat enters the continuous press, where high temperature and pressure cure the adhesive, forming a continuous board. Press temperature, pressure, and speed are automatically adjusted based on board thickness and process parameters.
6. Cooling & Cutting
After exiting the press, the continuous board passes through a cooling carousel to lower its temperature. It is then cut to standard dimensions (e.g., 4×8 ft) by the trimming saw.
7. Post-Processing & Packaging
Depending on requirements, boards may be sent to the sanding line for thickness calibration and surface finishing. They are then inspected, stacked, packaged, and stored or shipped.
8. Fully Automated Control
The entire production line is monitored and controlled from a central control room. Key parameters such as temperature, pressure, and moisture content are collected in real-time, enabling closed-loop process adjustments and fault alerts to ensure stable and efficient production.
Key Features & Benefits
1. High Automation & Intelligence: The entire line is equipped with advanced PLC control systems and HMI interfaces, enabling real-time monitoring, data logging, and automatic parameter adjustments. This significantly reduces manual intervention, ensuring product consistency and uninterrupted production.
2. Exceptional Durability & Reliability: All critical components, including the chipper, dryer, screener, former, and continuous press, are constructed from high-strength wear-resistant materials and manufactured with precision machining. The robust structure and high safety margins allow the system to withstand intensive, 24/7 industrial operations, minimizing unplanned downtime.
3. Energy-Efficient Design: Recognizing that drying and pressing are major energy consumers, our equipment incorporates optimized heat recovery systems, high-efficiency insulation, and variable frequency drive technology. This effectively reduces energy consumption, lowers operating costs, and aligns with eco-friendly production standards.
4. Precise Process Control: From particle geometry control and adhesive blending to mat forming and the pressing curve, every stage is precisely managed. This ensures the final panels possess superior physical and mechanical properties, such as high static bending strength, high internal bond strength, and low thickness swelling.
5. Flexible Customization: We tailor the process design and equipment configuration based on the customer's raw material characteristics (e.g., poplar, pine, eucalyptus), target capacity (from 50,000 to over 300,000 m³/year), and final product specifications, ensuring a perfect match for actual operational needs.
6. Comprehensive After-Sales Service: We provide full lifecycle support, including plant layout planning, foundation guidance, equipment installation and commissioning, personnel training, and long-term spare parts supply and technical assistance. This guarantees a smooth project launch and sustained high efficiency.
Applications
The particleboard produced by this line is widely used in furniture manufacturing, interior decoration, construction formwork, packaging, flooring substrates, and more, making it an ideal choice for modern wood-based panel production.
