A ce high quality ring die wood pellet maker machine can turn biomass wood crop straw waste into treasure

A wood pulverizer and a ring die wood pellet machine can process the remaining burned crop straws in rural areas into new energy fuels for heating in winter and cooking and boiling water in summer. Recently, experts from China New Energy Research Institute saw this magical device when Henan Deen Machinery inspected new energy and environmental protection equipment. The working mechanism of RICHI wood pellet machine: adopts the principle of interaction between the pressing force and the friction force between the pressure wheel and the mold to make the material get shape. 

There is no need to add any additives or binders during the processing of the pellet making materials. Straw and other materials contain a certain amount of cellulose and lignin. The lignin is a structural monomer in the material and is a phenylpropane-type polymer compound. It has the function of strengthening cell wall and binding cellulose. Lignin is non-crystalline, the main part is insoluble in any solvent at room temperature, has no melting point, but has a softening point. When the temperature reaches a certain value, the softening and cohesive force of lignin will increase, and under a certain pressure, the cellulose molecular cluster will be dislocated, deformed, and stretched. The adjacent biomass particles in the interior will engage each other, recombine and be suppressed. forming. The working process of RICHI hot sale wood pelletizing equipment: It can be divided into 4 areas, namely, feeding area, pressing area, kneading area and forming area.

1. Wood pellet press machine feeding area: the material is not subject to mechanical external force at all, it is in a natural loose state, but it is affected by the centrifugal force generated by the reversal of the ring die ring, so that the powder material is tightly attached to the inner ring of the ring die.

2. Wood pellet milling machine compaction zone: With the rotation of the die roll, the material enters the compaction zone. In this area, due to the kneading effect of the die roll, the powder particles move relative to each other, and the pores gradually decrease. With the acceleration of the material moving forward, the squeezing force is gradually added, and the pores are smaller, but the powder particles are basically not deformed.

3. Kneading area of ​​wood pellet making machine: In the kneading area, the gap between the die rolls becomes smaller, the kneading force increases sharply, the powder particles are further tightened and inlaid, the contact surface between the powder particles increases and the joint is strengthened, and the powder particles occur It is deformed and has a better connection, and the compacted powder is squeezed out to the die hole together. Saturation of a length of the die hole is used to form granules. The material in this section will undergo elastic and plastic combined deformation, and the density of the material after extrusion will reach about 1.1-1.3g/cm3.

4. Wood pellet maker machine forming area: the die hole is filled with the fuel cylinder that has been compacted and formed, and the newly squeezed powder material is continuously received inside the die hole, so that the fuel cylinder is pushed to the outside and discharged from the mold. At this time, the kneading force will defeat the sum of the friction force of the material column in the die hole, and the shaped pellets will be squeezed out.
