What is the reason for the poor molding of the fuel pellet machine?

When the fuel pellet machine produces pellet feed, the heating temperature not only affects the formability of the raw materials, but also affects the working efficiency of the biomass pellet machine. The heating temperature should be adjusted to a suitable range. If the temperature is too low, not only the raw material cannot be molded, but also the power consumption increases. As the temperature increases, the motor power consumption decreases, but the molding pressure decreases and the molded product is extruded. At the same time, the density becomes smaller, it is easy to break and break, and the surface of the particles is overheated and burned, resulting in larger smoke.

Although the biomass pellet machine does not have external heating, during the molding process, the friction between the fuel and the machine parts can also heat the temperature of the raw material to 140 degrees, which can also soften the lignin contained in the raw material and act as an adhesive. function, and finally cooled and formed. Of course, the above situation is under the ideal conditions of many factors such as the strength of the biomass raw material, the pressing pressure, the mold compression ratio, the feed material, and the moisture content of the raw material.

If there is no material discharging, it is probably because the material moisture is not suitable. If the moisture content of the material is too high or too low, it may block the mold holes and prevent normal discharge. Generally, the moisture content of materials should be controlled between 10% and 15%. Worn molds and pressure rollers. The mold pressure plate and pressure roller are key components of the pellet machine and are easily worn due to long-term use. Worn parts will cause the gap between the mold and the pressure roller to increase, affecting the suppression and discharge of the material.
