Wood pellet machine can process various forestry wastes into burnable pellets.

The DEXI wood pellet machine efficiently converts diverse forestry and wood waste—including logs, planks, scrap wood, sawdust, wood shavings, leaves, branches, trunks, roots, wood blocks, discarded furniture, and sawmill residues—into clean, eco-friendly energy pellets. These pellets are characterized by low emissions, a controlled combustion rate, and extended burn time. Available in standard diameters of 6–12 mm, pellet dimensions can also be customized to meet specific client requirements.

Wood pellets, as a clean and efficient biomass fuel, are mainly used in four major areas.

1. Industrial and District Heating – Replaces coal in facilities such as factories, schools, hospitals.

2. Power Generation – It fuels dedicated biomass plants or supports coal co‑firing in power generation.

3. Residential Heating – Supplies domestic heating and hot water through specialized pellet stoves and boilers.

4. Industrial Thermal Energy – Provides a reliable heat source for drying and thermal processes across sectors.

Main Advantages - As a renewable energy carrier, biomass pellets offer low emissions, high energy density, and compatibility with automated handling and conveyance systems, positioning them as a critical enabler of the transition to cleaner energy.

The wood pellet machine plays a crucial role in the entire production line, as it determines both the overall output capacity and the final pellet size.

① Chipping:This stage processes biomass waste into 3–5 cm wood chips, preparing the material for crushing.

② Crushing:The wood chips are further ground into fine sawdust with a pellets size of 3–5 mm for pelletizing.

③ Drying:Using a dryer, the moisture content is reduced to about 13%—the ideal level for making pellet formation.

④ Pelletizing:The dried material high pressure into wood pellets, typically with diameters ranging from 6 to 12 mm.

⑤ Cooling:The pellet cooler reduces the temperature of the pellets (85–90°C) to ambient temperature to store.

⑥ Packaging:The cooled pellets are automatically weighed and packed into bags of 25–50 kg, followed by sealing.

⑦ Palletizing:Packed bags are systematically stacked onto pallets to facilitate safe, efficient handling and storage.

⑧ Wrapping:Pallets are stretch‑wrapped for secure stability and protection against moisture and contaminants.

DEXI exports to 116 countries every year, with over 2,800 equipment solutions delivered globally. Here are one examples from our many successful projects.

Country: Indonesia

Capacity: 3-4t/h

Raw materials: Wood shavings and Hardwood

After thoroughly evaluating the specific conditions and requirements from our client in Indonesia, DEXI engineered a fully customized wood pellet production line capable of processing 3–4 tons per hour.

The system is designed to efficiently handle raw materials including wood shavings and hardwood from local sawmills. Our integrated solution covers the complete workflow:

• 1. Crushing – uniform size reduction for consistent drying and pelletizing

• 2. Drying – moisture control optimized for tropical climate conditions

• 3. Pelletizing – high-density pellet formation with minimal fines

• 4. Cooling – stable temperature management to ensure pellet durability

• 5. Screening – removal of undersized pellet guarantee product uniformity

• 6. Packaging – automated weighing and bagging for ready-to-market output

Each stage incorporates equipment selected and tuned for the client’s material properties, throughput targets, and site layout. As a result, the plant now consistently produces high-grade wood pellets while achieving a strong return on investment through reliable output and optimized operational efficiency.
