Understanding the molding extrusion principle of biomass pellet machine is conducive to improving equipment troubleshooting skills and improving production efficiency. The core components of JNSHARE biomass pellet machine are ring die and pressure roller, and there are many die holes around the ring die. During molding, the biomass raw materials crushed into powder are sent into the ring die compression chamber, and then the motor drives the pressure roller to rotate. The material is evenly distributed to the periphery of the ring die by centrifugal force and brought between the pressure roller and the ring die, so that the ring die and the material, the pressure roller and the material, and the material and the material produce friction with each other, so that the cellulose and hemicellulose in the material are combined with each other. The heat generated by friction softens the lignin, and acts as a binder to bond the cellulose and hemicellulose together.
The entire molding process relies on the material between the die rollers and its friction force to extrude and shape the material outside the ring die. When the extrusion force is greater than the friction force, the material is squeezed into the die hole of the ring die, extruded outward, and formed, completing the entire pelletizing and compression process.
