一台木屑煤球机(通常称为木屑原木制造商)是压缩松散木材废物的专门生物量设备 (木屑, 剃须, 农业残留物) 变成统一, high-density briquettes suitable for fuel applications . These briquettes can burn cleaner and hotter than traditional firewood due to their low moisture content and high compactness. 在Weiwa机械, we specialize in providing top-tier solutions like the Sawdust 机器煤球 to help businesses turn waste into wealth.
- Screw Press vs. Piston Press: Screw-type extruders produce hollow, hole-through briquettes, increasing combustion efficiency, while piston presses yield solid blocks without central holes.
- Lignin Binding: High pressure and temperatures (typically around 280 °C) melt natural lignin in the sawdust, binding particles without added adhesives .
How It Works
Preparation of Raw Material
- Raw sawdust must be milled to < 5 mm particle size and dried to moisture < 12% for optimal briquetting .
- Optional pre-dryers and crushers ensure consistent feedstock quality .
加热 & Extrusion
- The machine’s heating rings raise the chamber temperature to ~ 280 °C, activating lignin .
- A rotating screw pushes material through a hardened steel mold under high pressure, forming logs of 50–70 mm diameter .
冷却 & Collection
- Briquettes exit the mold and quickly cool, solidifying into durable fuel logs ready for storage or carbonization into charcoal .
Charcoal made from Sawdust Log Maker
Key Features & Components
核心组件
- Spiral Propeller (Screw): Drives raw material forward; made from wear-resistant Cr40 steel for longevity .
- Heating Elements: External coils maintain stable temperatures; replacement coils recommended as spare parts .
- Molding Sleeves: Interchangeable hexagonal or square dies (4.8–5 cm) determine briquette shape and density .
- 发动机 & Drive System: Copper-core motors (18.5–22 kW) ensure high torque and extended service life .
Benefits of Using a Sawdust Briquette Machine
Economic Advantages
- Low Investment & Operating Costs: Core machinery investment is modest; power consumption ~ 11 kW for extrusion, total line ~ 26 kW, translating to 180–200 kWh/day .
- High Profit Margins: Briquettes can fetch higher prices than raw sawdust, creating new revenue streams.
- Business Opportunity: Compact production lines fit small to large-scale operations, enabling entrepreneurs to turn waste into marketable fuel.
环境的 & Operational Gains
- Eco-Friendly Fuel Substitute: Briquettes emit 13.8–41.7% less CO₂ and NOₓ than coal, reducing greenhouse gases.
- Sustainable Waste Management: Converts agro-forestry residues into value-added products, alleviating landfill pressure.
- High Heating Value: Briquettes deliver 19.3–20.5 MJ/kg, higher than many fossil fuels.
Applications of Sawdust Briquettes
- Residential & Commercial Heating: Efficient for stoves, fireplaces, and district heating.
- Industrial Boilers & Power Plants: Co-firing with coal or as standalone fuel in biomass-dedicated boilers.
- 木炭生产: Further processing in machines like our 木屑木炭机器 yields high-quality charcoal.
- Animal Bedding & Feed Additives: Pelletized sawdust briquettes can serve as livestock bedding or feed supplements in pastoral applications.
Choosing the Right Sawdust Log Maker
When selecting a sawdust log maker, consider:
- Material Type: Ensure compatibility with your biomass source.
- Production Capacity: Match the machine’s output with your energy needs.
- End Use: Determine if the briquettes will be used directly or further processed.
For those looking to produce charcoal briquettes, our 木炭制造机器 offers an integrated solution.
