China Straw Pellet Machine

The working principle of the China straw pellet machine is mainly to use the interaction of extrusion force and friction between the high-pressure screw or pressure wheel and the mold to extrude biomass materials into solid blocks for molding. Specifically:
On the one hand, the straw pellet machine feeds raw materials into the machine through a feeding device. The feeding device is driven by a motor and transmitted to the reducer through a V-belt, which drives the spindle to rotate. Then, using components installed at the end of the spindle (such as hammers or connecting rods), the material is thrown around and crushed. The crushed material flows out through the sieve holes for use in the next process.
On the other hand, the pre treated material enters the molding area of the straw pellet machine. Here, the material is subjected to strong compression and friction between the high-pressure screw or roller and the mold, gradually being compressed into dense particles. During this process, natural binders such as lignin in the material soften and bond under pressure and temperature, giving the particles a certain strength and stability.
Finally, the formed particles are extruded from the mold and can be packaged and stored after cooling and drying. These particulate fuels have the advantages of high density, high calorific value, easy storage and transportation, and are widely used in rural heating, biomass power generation, industrial boilers and other fields.
In summary, the straw pellet machine converts biomass materials into pellet fuel through mechanical compression. Its working principle is simple and efficient, providing strong support for the utilization of renewable energy.
