Biomass briquettes are a type of clean fuel made from compressed agricultural and forestry waste. Common raw materials include sawdust, rice husks, peanut shells, and corn stalks.
These fuels have high density, long burning time, and are easy to store and transport. The sawdust briquette machine is the core machine in the manufacturing process.
Biomass briquette production process
A complete production process typically includes the following steps:
- Raw material preparation
- Crushing and processing
- Briquetting
Brquetting is the most critical step in the entire production line, as it determines the density, hardness, and combustion performance of the fuel briquettes.
Raw material requirements
The biomass briquette making machine can process a wide range of raw materials, commonly including: Sawdust, rice husks, wheat straw, corn stalks, peanut shells, coconut shells, palm shells, bamboo shavings, and bagasse.
Key specifications:
- Moisture content: 8%–12%
- Raw material size: ≤6mm
- Free of stones, metal, and other impurities
Working principle of biomass briquette machine
The sawdust briquette machine uses high-temperature and high-pressure extrusion molding technology to compress loose wood chips into high-density briquette fuel.
Working process:
- Raw material enters the hopper
- A screw propeller continuously conveys the material
- A heating coil heats the die
- Lignin softens and binds the fuel
- High-pressure extrusion molding continuously produces fuel briquettes
Advantages of sawdust briquette making machine
- Automated continuous production ensures stable operation and significantly reduces labor costs.
- The finished product has a uniform shape, high hardness, and long burning time, making it a good substitute for coal.
- Raw materials are widely available, transforming agricultural and forestry waste into profitable products.
- The operation is simple, requiring only one person. This saves on labor costs.
