Introduction: A Pellet Production Line Worth Your Attention

If you're planning to build a wood pellet plant, understanding successful, large-scale projects is key to making informed decisions. This article introduces a fully operational pellet production line we engineered and installed for a client in Thailand. With two parallel production lines and an annual output of 120,000 tons, this system is designed to process rubber wood with 50% moisture content, maximizing efficiency, automation, and sustainability.

Whether you're researching how to make wood pellets, considering the cost of a pellet plant, or looking for reliable pellet machine manufacturers, this case study offers real-world insights.

① Chipping Section: Preparing Raw Material for Efficiency

Rubber wood logs with 50% moisture are transported via a vibrating conveyor into a wood chipper, where they are cut into 20 cm pieces. These chips are temporarily stacked outdoors to allow natural evaporation, significantly reducing the load on the drying system.

② Crushing Section: Sizing Down for Pellet Quality

Once pre-dried, the wood chips are transferred through a twin-shaft feeder into a hammer mill. This step produces finer particles essential for consistent pellet quality. A magnetic separator is also integrated to remove any metal contaminants, protecting downstream equipment.

③ Sieving & Drying: Preparing the Perfect Pellet Raw Material

The sawdust produced is screened by a drum screen to ensure uniform size before entering a large rotary dryer. This step achieves the optimal moisture content for pelleting, around 10–12%.

④ Pelleting Section: The Heart of the Production Line

Dried material is lifted into a hydraulic storage silo. A top-distribution screw conveyor and bottom hydraulic feeder ensure continuous, even flow. Belt conveyors deliver the material to a twin-shaft buffer silo, which then feeds it into six high-efficiency pellet machines.

⑤ Cooling & Screening: Ready for Storage

Freshly extruded pellets are cooled in an advanced counter flow cooler and screened via a vibrating separator to remove fines. A belt scale system records real-time output data per hour, day, and month—an essential feature for any smart production setup.

⑥ Conveying & Storage: Efficient Bulk Handling 

Finished pellets are moved by a 48-meter belt conveyor and a 96-meter mobile stacker, which delivers product directly to the storage yard. This automation ensures minimal handling and faster logistics.

Full Automation & Dust Control: Smarter, Safer Operation

Full automation means minimal labor is needed. From PLC control cabinets to central monitoring systems, the plant allows precise control over every stage.
At the same time, a central dust collection system ensures a cleaner, safer workplace, in compliance with modern environmental standards.

Conclusion: Planning a Pellet Project? This Design Is Worth a Look.

This Thai pellet plant is a prime example of how to design and operate a high-output, energy-efficient wood pellet production line with advanced automation and reliable pellet machines.
