How Can a Small-Scale Wood Pellet Production Line Turn Waste into Renewable Fuel?

With growing attention to renewable energy and sustainable biomass solutions, the 0.8–1t/h Small-Scale Wood Pellet Production Line provides an efficient method for converting forestry and agricultural waste into high-quality biomass pellets. Designed for both home and industrial applications, this production line transforms sawdust, wood chips, and crop residues into fuel for home fireplaces, power plants, and even animal bedding.

Q1: What raw materials can this production line handle?
The system is versatile, able to process a wide variety of agro-forestry and industrial waste. Materials include wood chips, sawdust, branches, bark, straw, rice husks, sunflower stalks, peanut shells, coffee husks, and more. The raw materials must meet a size requirement of 3–5 mm and a moisture content of 10–15% for optimal pelletizing results. The final pellets are adjustable in diameter (6–12 mm) and length, depending on customer requirements.

Q2: What is the workflow of the pellet production line?

1. Wood Chipping: A drum chipper reduces logs and branches to small chips, generally under 5 cm in size.

2. Grinding: A hammer mill system further reduces the chips into fine sawdust suitable for pellet production.

3. Drying: Moisture content is reduced from 50% to 13–15% using a rotary dryer, the ideal range for pelletizing.

4. Pelletizing: Using a 4Cr13 ring die pellet mill, equipped with SIEMENS motors, SKF bearings, and high-precision gear transmission, the sawdust is pressed into pellets. A forced feeding system ensures smooth operation.

5. Cooling: The produced pellets exit the pelletizer at around 70°C and are immediately cooled to room temperature, increasing hardness and durability.

Q3: What are the main technical specifications?
The production line offers multiple models:

• Model 350: Capacity 0.8–1t/h, power 75 kW, weight 2.8 tons

• Model 420: Capacity 1–1.5t/h, power 90 kW, weight 3.2 tons

• Model 508: Capacity 1.5–2t/h, power 132 kW, weight 5.3 tons

• Model 650: Capacity 2.5–3t/h, power 200 kW, weight 9 tons

Q4: What makes this production line stand out?
The line is fully customizable, including final pellet size, motor brand, voltage, and even the color of the equipment. Its stainless steel ring die and press roller shell enhance durability and reduce wear. Additionally, engineers can be dispatched for installation and commissioning, ensuring smooth startup.

In conclusion, the 0.8–1t/h Small-Scale Wood Pellet Production Line provides an efficient, customizable, and environmentally friendly solution to convert wood and agro-forestry waste into renewable fuel. By turning low-value biomass into high-density pellets, it promotes sustainability while creating economic opportunities for small and medium-sized enterprises.
