In the industry of wood pellet fuel pellet, the process of pulverized wood pellet by water, heat conditioning and extrusion through the wood pellet machine and forced through the ring die hole polymerization is called pelleting, I will introduce the pelleting process of the wood pellet machine.
In the working process of the wood pellet machine, the press roller is driven by the main power of the motor to rotate clockwise at 85 revolutions per minute; As the tempered wood sawdust material enters the pelleting chamber, the material begins to be absorbed into the working area, and the press roller also begins to rotate clockwise by the action of friction in the working area. With the rotation of the roller, the ingested material moves forward faster, and the extrusion pressure and the density of the material gradually increase. When the extrusion pressure increases enough to overcome the friction between the material in the die hole and the inner wall, the wood chip material with a certain density and bonding force is extruded into the ring die hole.
Due to the continuous rotation of the press roller, the material is continuously extruded into the ring die hole, so the material in the ring die hole is continuously extruded out of the ring die hole after forming, and is cut off by the cutter to form granular wood pellet.
