Creating Biomass Pellets from Sawdust: A Valuable Fuel Source
Sawdust, a by-product of wood sawing, lacks burning efficiency. However, it’s an ideal material for pelletizing. The natural lignin in wood acts as a binder for high-quality, dry, and durable pellets, ideal for fuel. Utilizing sawdust for pelletizing offers a smart way to convert wood waste into profit-boosting fuel. Applications range from household heating to large-scale industries.
Distinct Properties of Biomass Pellets from Various Sources
Feedstock Bulk Density (kg/M3) Energy Content (MJ/kg) Ash Content (%)
Key Considerations for Sawdust Pelletizing
1. Material Collection: Transportation costs are critical. Avoid long-distance transmissions.
2. Particle Size: Sawdust length, under 6mm, directly impacts pelletizing efficiency.
Process of a 1T/H Sawdust Pellet Plant
1. Sawdust Crushing:
Use a wood hammer mill to reduce sawdust size. The CF500B model is ideal for 1t/h output, crushing sawdust into small particles via rotating hammers.
2. Drying:
Rotary drum dryer ensures optimal 10-15% moisture content, enhancing pellet quality and fuel efficiency.
3. Pelletizing:
Adopt a 420 model ring die wood pellet mill with 8mm, 10mm, or 12mm ring dies for optimal fuel pellet combustion.
4. Cooling:
A wood pellet cooler reduces pellet temperature to 3-5℃ above ambient and moisture content to 12-13% for storage.
5. Packaging:
Automatic Weighing & Packing Systems protect pellets from dampness and dust.
Advantages of Sawdust Fuel Pellets
– Cost-effective alternative with stable pricing unaffected by inflation.
– Environmentally sustainable and carbon-neutral after burning.
– High calorific value and increased bulk density for efficient heating.
– Convenient, easy to light, and store while being transport-friendly.
1T/H Sawdust Pellet Plant Applications
Raw Materials: Process materials like bark, wood shavings, crop straw, rice husk, and more.
Industrial Use: Widely applied in biomass power stations, wood processing factories, and fuel plants.
