The straw briquetting machine is also called a biomass briquetting machine for briquetting stem biomass. The straw briquetting machine must first use a haymaker or kneading machine to crush it into raw materials with a length of 20 to 50 mm and a moderate moisture content. After passing through the feeding conveyor, it enters the briquetting machine for processing and is extruded into blocks. The block density is 0.6 to 1.0 g/cubic centimeter, which is convenient for transportation and storage.

                   The biomass briquetting machine consists of a feeding conveyor, a compressor and a discharging machine. The compressor consists of a frame, motor, feed port, transmission system, pressure roller, ring die, electric heating ring, discharge port and other parts. The working principle of the biomass briquetting machine: cut or knead the straw or grass to be pressed, with a length of less than 50mm, and a moisture content controlled within the range of 10 to 25%. The material is sent to the feed port through the feeding conveyor. , through the rotation of the main shaft, the pressure roller is driven to rotate, and through the rotation of the pressure roller, the material is forced to be extruded from the mold hole into blocks, and falls from the discharge port. After cooling down (moisture content cannot exceed 14%), it is bagged and packaged .
