Particle production section: including chipping, slicing and other steps. Small-diameter wood and branch wood are chipped after metal detectors remove metal, and then stored separately according to tree species.

Drying and sorting section:

 Wet particles are dried by drum dryers, and the dried particles are screened to ensure quality.

Gluing section: 

Surface and core particles are glued separately, and the glue is injected into the glue mixer through an automatic metering system.

Paving and hot pressing section: 

The particles after gluing are laid into slabs by a paving machine, and then enter the hot press for hot pressing.

How Continuous Pre-Press Revolutionizes MDF, OSB, and Particleboard Production

In the high-stakes, high-volume world of engineered wood panel manufacturing – producing MDF (Medium Density Fiberboard), OSB (Oriented Strand Board), and Particleboard (PB) – efficiency, quality, and consistency are non-negotiable. While the mighty continuous press often grabs the spotlight, a critical component working tirelessly upstream is the Continuous Pre-Press Machine. This unsung hero plays a pivotal role in determining the final product's quality, the production line's speed, and the overall profitability of the operation. Manufacturers like SHANDONG MINGHUNG OSB&MDF MACHINERY EQUIPMENT MANUFACTURING CO., LTD., understand this deeply, engineering robust continuous pre-presses designed for peak performance and enduring durability.

Why Pre-Press? The Critical Foundation

Before the mat of wood fibers, strands, or particles enters the high-pressure, high-temperature continuous press, it's a fragile, airy structure. Attempting to feed this uncompacted mat directly into the main press would be disastrous:

1.  Mat Collapse: The high nip pressure at the press entrance would simply blow the uncompacted mat apart, causing stoppages, material waste, and potential damage.

2.  Poor Density Profile: Without initial compaction, achieving the crucial uniform density gradient from surface to core in the final panel becomes extremely difficult, leading to weak spots, warping, and poor machining characteristics.

3.  Reduced Production Speed: The main press would be forced to slow down significantly to allow time for initial compression and deaeration within its initial section, becoming a bottleneck.

4.  Increased Glue Consumption & Energy Use: An uncompacted mat has low thermal conductivity. Pre-compaction removes air, allowing heat from the main press to penetrate faster and more evenly, reducing curing time and energy consumption. It also brings particles closer, requiring less resin for effective bonding.

5.  Surface Defects: Loose surface layers can lead to blowouts, rough surfaces, or delamination when entering the main press.

This information shows the complexity and efficiency of the automatic particleboard production line, making it one of the important equipment in the wood processing industry.

In a particleboard production line, both diamond roller paving machines and airflow paving machines are used to distribute resin-coated wood particles into a uniform mat before pressing. However, their design, operation, and suitability vary significantly. Below is a detailed comparison and guidance on selecting the right system for your needs:

1. Diamond Roller Paving Machine

Design & Working Principle  

Mechanism: Uses a rotating roller with a textured "diamond" pattern (raised ridges or grooves) to mechanically spread and compact particles.  

Particle Distribution:

Parts for forming machine

Parts for forming machine

Particles are fed onto the conveyor belt, and the diamond roller rotates to distribute and lightly compact them.  

The diamond pattern breaks up particle clumps and ensures even spreading.  

Layering: Typically used for single- or multi-layer mats, especially for coarse or mixed particles.  

Key Features

Particle Size Compatibility: Ideal for coarse to medium particles(e.g., wood chips, recycled materials).  

Density Control: Adjusting roller speed, pressure, and gap settings regulates mat density.  

Compaction: Provides light pre-compaction during spreading, reducing air pockets.

Advantages

Robust and simple design with minimal maintenance (fewer moving parts than squirrel cage systems).  

Effective for high-volume production with consistent raw materials.  

Lower energy consumption compared to airflow systems.  

Disadvantages  

Limited ability to handle fine particles (risk of uneven surface layers).  

Less flexibility for graded density profiles (e.g., fine surface layers over coarse cores).  

2. Airflow Paving Machine

Design & Working Principle  

Mechanism: Uses pneumatic air jets to suspend particles in an airstream and distribute them onto the conveyor belt.  

Particle Distribution:  

Particles are blown through adjustable nozzles, allowing precise control over layering and density.  

Air pressure and nozzle angles can be fine-tuned for graded density profiles.  

Layering: Excels at multi-layer or graded-density mats (e.g., smooth surface layers over a coarse core).  

Key Features  

Particle Size Compatibility: Best for fine particles (e.g., sawdust, surface-layer fines).  

Density Control: Real-time adjustments via airflow velocity and nozzle positioning.  

Surface Quality: Produces ultra-smooth surfaces for laminated or furniture-grade boards.  

Advantages  

Superior surface finish and density uniformity.  

Flexible for complex layering (e.g., 3-layer boards with varying particle sizes).  

Minimal particle segregation.  

Disadvantages

Higher energy consumption (compressed air systems).  

Higher initial cost and sensitivity to raw material moisture content.  

Less effective for very coarse or heavy particles.  

Key Differences Summary

How to Choose Between Them  

1. Particle Size & Raw Material

Choose Diamond Roller if:  

Your raw materials are coarse or mixed (e.g., wood chips, agro-residues).  

You prioritize simplicity and low energy costs.  

Choose Airflow if:  

You use fine particles(e.g., sawdust) for surface layers.  

You need graded-density boards (e.g., furniture panels).  

2. Board Quality Requirements

Diamond Roller: Suitable forstructural or industrial boards (e.g., packaging, construction) where surface smoothness is less critical.  

Airflow: Essential for high-end boards requiring flawless surfaces (e.g., laminated furniture, flooring).  

3. Production Volume & Cost

Diamond Roller: Better for high-volume lines with stable raw materials (lower operational costs).  

Airflow: Justified for premium products** where quality outweighs higher energy/maintenance costs.  

4. Flexibility & Automation  

Diamond Roller: Limited flexibility but easier to operate.  

Airflow: Offers advanced automation (e.g., IoT sensors for real-time density adjustments).  

Industry Trends

Hybrid Systems: Some plants combine both:

Airflow for surface layers (fine particles).  

Sustainability: Airflow systems reduce material waste through precise distribution.  

Smart Manufacturing: Airflow machines increasingly integrate AI for adaptive particle distribution.
