Particleboard production is a highly automated, continuous process. Its core involves processing wood or other lignocellulosic materials into flakes, applying adhesive, and then pressing them into panels under heat and pressure. The main steps are as follows:
1. Raw Material Preparation
Chipping: Logs, small-diameter wood, slash, or wood processing residues (e.g., slabs, trimmings) are processed through a chipper into uniform wood chips.
Washing & Screening: Chips are washed to remove impurities like sand, stones, and metals. They are then screened to separate oversized and undersized chips. Qualified chips proceed; unqualified ones are returned for reprocessing.
2. Flake Preparation & Classification
Flaking: Qualified chips are fed into a Ring Flaker. Under the action of the knife ring and bed knife, they are shaved into thin flakes. This is a key step determining flake geometry and quality.
Re-crushing: Some overly thick flakes or chips need to be broken down in a re-crusher (e.g., hammer mill) to obtain finer particles.
Drying: Wet flakes are fed into a rotary drum dryer or pneumatic flash tube dryer, where hot air reduces their moisture content from 40%-60% to the ideal range of 2%-4%.
Screening & Grading: Dried flakes are classified by size via multi-deck vibrating screens. Typically separated into fine face flakes, coarse core flakes, and oversize/fines (dust, often used as fuel). This grading enables the optimized "fine-face/coarse-core" structure for a smooth surface and core strength.
3. Blending
Resin Application: Graded face and core flakes are sent to separate blenders (typically high-speed centrifugal blenders). Here, flakes are thoroughly mixed with precisely metered adhesive (usually Urea-Formaldehyde UF or Melamine-Urea-Formaldehyde MUF resin), hardener, waterproofing agent (wax emulsion), etc.
Proportioning & Conveying: Face and core flakes are conveyed via belt scales or pneumatic systems to the forming station in preset ratios.
4. Mat Forming & Pre-pressing
Forming: This is the key station for achieving custom sizes and mat structure. Resinated flakes are spread evenly by a mechanical or air-laid forming station onto a moving caul plate (or steel belt) to form a multi-layered mat of specific thickness and width with a "fine-face/coarse-core" structure. The former's width and outlet determine the panel width.
Pre-pressing: The fluffy mat enters a pre-press. It applies significant mechanical pressure for initial compaction, removing most air, increasing initial strength, and forming a firm mat easier to handle and preventing blow-out in the hot press.
5. Hot Pressing & Curing
Hot Pressing: The mat enters the hot press. For custom sizes and high output, a Continuous Flat Press is standard. The mat passes between two massive, heated steel belts while an array of dozens of hydraulic cylinders above applies uniform pressure and high temperature (typically 180-220°C). The heat melts and cures the adhesive rapidly, bonding the loose flakes into a dense panel. This is the core step determining final thickness, density, and mechanical properties.
6. Post-processing
Cooling & Conditioning: Panels exiting the press are very hot (>90°C) and enter a star cooler for forced cooling to stabilize internal stresses and evaporate excess moisture.
Trimming & Cutting: Cooled panels first pass through trim saws to remove irregular edges. Then, this is the core link for achieving "custom sizes". Panels are sent to a cross-cut saw or a large gantry cutting center to be cut to the exact length and width required by customer orders. This differs fundamentally from standard lines producing only fixed sizes (e.g., 1220x2440mm).
Sanding: The custom-sized rough panels are calibrated and sanded by a wide-belt sander (usually with multiple heads for coarse and fine sanding) to achieve precise final thickness and a smooth, uniform surface.
Testing & Grading: Finished boards are tested (e.g., thickness, density, MOR, IB, formaldehyde emissions), graded according to quality standards, packaged, and stored.
1. Raw Material Handling System
Debarker (if needed): Uses rotating drums or cutting heads to remove bark from logs.
Drum Chipper: A large rotating drum equipped with flying knives. Wood is fed in and cut into chips by the knives.
Screen: Multi-deck vibrating screens for sizing wood chips.

2. Flake Preparation System
Ring Flaker: Core component is a high-speed rotating knife ring and a fixed bed knife. Chips are fed in and flung centrifugally against the inner ring, being shaved into flakes by the gap between the ring and bed knife.
Hammer Mill: Uses rapidly rotating hammers to strike and break down larger chips or flakes.
Rotary Drum Dryer or Pneumatic Dryer: The former is a slowly rotating, inclined drum through which hot air flows to dry flakes; the latter uses high-speed hot air in a tube for instant drying.
Particle Screening System: Multi-deck vibrating screens for precise size classification of dried flakes into face, core, and waste material.

3. Blending System
Metering Bins & Scales: A series of bins and belt scales to precisely control the proportion and flow of face and core flakes.
High-Speed Blender: A drum with high-speed rotating paddles or discs where flakes and atomized resin are vigorously tossed and mixed to ensure uniform coating.
4. Forming and Pre-pressing System
Mechanical/Air-laid Forming Station:
Mechanical: Uses multiple metering bins and forming heads with fluted rolls to spread flakes evenly onto the belt.
Air-laid: Uses air suspension to blow flakes into a forming chamber for even descent. Achieves better layer separation.
Continuous Belt Pre-press: Applies gradual pressure via two large pressing belts for initial compaction of the fluffy mat.

5. Hot Pressing System
Continuous Flat Press: The heart of a modern high-capacity line. Main components include: a massive frame, two circulating heated steel belts, a complex array of hydraulic cylinders (applying pressure), a heating system (usually thermal oil), drive rolls, and a control system. The mat is continuously conveyed and cured under pressure and heat between the hot steel belts.
6. Post-processing System
Cooling Star Cooler: Multi-level roller conveyor for forced cooling of panels in an "S" pattern.
Edge Trimmer: Fixed saw units for trimming the two long edges of the panel.
Cross-Cut Saw: Cuts the continuous panel strip to the required length. Crucial for custom sizing, its positioning accuracy and flexibility are paramount. A large CNC gantry cutting center can also be equipped to cut large master panels directly into any required smaller sizes.
Multi-head Wide-belt Sander: Typically 4-6 or more heads (coarse/fine combination), wide sanding belts, high-power motors for high-precision calibration and sanding of both panel surfaces.

7. Auxiliary Systems
Thermal Energy Plant (TEP): Provides heat (thermal oil/steam) for core processes (drying, pressing), often fueled by wood waste (bark, sander dust, sawdust).
Dust Extraction System: Extensive network of pipes and dust collectors (e.g., bag filters).
Automation Control System (DCS/PLC): The Distributed Control System is the "brain" of the entire line, monitoring/regulating all equipment parameters for stable operation and storing/managing production parameters for custom sizes.
1. Adjustable Forming Width: The outlet width of the forming station can be adjusted mechanically or automatically within a certain range, changing the mat width—the basis for custom panel width.
2. Flexible Cutting System: The line's "brain" (control system) can receive orders for specific lengths and widths.
For Continuous Presses: A downstream cross-cut saw receives instructions to make precise cuts on the moving panel strip at specific positions, yielding different board lengths.
For Large Master Panels: The line can be equipped with a large CNC Cutting Center at its end. Panels are first pressed into large formats (e.g., 4ft x 24ft). The cutting center then automatically and efficiently cuts them into dozens of different smaller sizes based on optimized nesting diagrams from software, greatly improving material yield and production flexibility.
3. Rapid Thickness Change: Modern continuous presses use advanced hydraulics and controls to change the press opening and pressure profile relatively quickly (minutes to tens of minutes), enabling fast transitions between producing different thicknesses.
4. Production Management Software: Advanced MES (Manufacturing Execution System) integrated with the line control system can receive and manage custom orders from an ERP, automatically generating production instructions and cutting plans to ensure correct dimensions, quantities, and quality requirements are executed seamlessly.
