Straw briquette machine can use wheat, corn, sorghum, peanut shells, forage grass, leaves and other straws as raw materials, and straw that is not rotten, mildewed, soilless and unpolluted should be selected. In the production of straw briquettes, there should be a large enough space to store the required raw materials. At the same time, strict fire prevention measures should be formulated and enough fire-proof materials should be prepared. The moisture content of briquette raw materials should be kept between 15% and 25%, and those with high moisture content should be dried, and those with moisture content lower than 14% should be added with water. Before pressing, the straw should be crushed and kneaded, and then dried.

Working principle of straw briquette machine: Cut or knead the straw or forage grass to be pressed, the length of which is less than 50mm, the straw briquette machine is driven by the motor to rotate, the press die and the press roller in the machine move relatively, the raw material pass through the feeding conveyor, then enter the briquette machine, squeeze into blocks, and fall from the discharge port. After cooling (the water content cannot exceed 14%), packaged the manufactured briquettes. The produced straw briquettes overcome the weakness of light weight, large volume, easy exposure to wind, rain, snow, fire and other external conditions, and meets the commercialization requirements.

Briquetting machine has the advantages of high automation, high output, low price, low power consumption and simple operation. If there is no power equipment, diesel engine can be used instead. The straw briquette machine has strong material adaptability: it is suitable for the molding of various biomass raw materials, and the straw briquette machine can process and shape straw from powder to 50mm in length. Automatic adjustment function of pressing wheel of straw briquette machine: the pressure angle is automatically adjusted by using the principle of bidirectional rotation of thrust bearing, so that the materials will not be crowded or stuffy, and the stability of discharging and molding will be ensured. Straw briquette machine is easy to operate and convenient to use: it has high automation degree and less labor, and can be fed manually or automatically by conveyor.
