Biomass briquetting machine is also called briquettes or straw briquetting machine. The briquetting equipment is suitable for the fluffy material such as straw and sawdust that can be produced a high density of biomass briquette. Straw briquetting needs the ensilage machine or rubbing machine to crushing to the length of 20 ~ 50 mm material. Through extreme pressure, the briquette is formed. The density of briquette is 0.7 ~ 1.2 g/cm3. The benefit of briquette is convenient to transportation, save and usage. Straw briquette overcomes the lightweight, large volume, and easily affected by environmental conditions such as rain or snow fire. It can be satisfied with the demand of the commercialization, which can be sold as fuel or animal feed. Biomass briquettes production line included feeding conveyor, briquettes, and discharging machine, and the operation of distribution cabinets. While, the briquetting machine included equipment rack, motor, feeding port, transmission system, pressure roller, horizontal ring die, discharging port and other parts.

    The straw, grass, and wood chips put into cutting or grinding machine to be fiber. The fiber length less than 50mm. The moisture content is between 12% and 25%. The feeding conveyor sends material into the feed port. Through the spindle rotation to drive the roller rotation, and then through the rotation of the roller, the material was extruded by nubby shape from the horizontal hole. and falling the discharging port. The model hole can be a square or circular ring.
