After a long period of use and wear, the feed pellet machine will more or less show some so-called undesirable phenomena. In this case, we need to know what preventive measures for the bad phenomenon of the pellet feed machine, so as to prolong the service life of the feed machine-pellet machine. Based on years of experience and summary, we have summed up the following six points, and hope to help you in your future work.
1. The particles have axial cracks or radial cracks, and the pulverization rate is high, and the output is low. The reason for this phenomenon may be that the tempering temperature cannot be reached and the material is not mature enough. The specific solution should be increased. Conditioning temperature, increasing the amount of steam during conditioning; it may also be that the cutter is far away and blunt, so that the particles are short or torn rather than cut;
2. The particle surface is not smooth, and the powdering rate is high. It may be that the ring die compression is relatively small, and the compression hole should be increased;
3. The particle surface is smooth, but the hardness is too high, it may be that the ring die compression is relatively large, the ring die compression ratio should be reduced;
4. When the particle moisture is too high, the production output is low, and the phenomenon of machine blockage often occurs. It may be that the pressure reducing valve cannot play the pressure reducing effect or the steam trap cannot play the hydrophobic role. The pressure reducing valve should be adjusted so that it enters the conditioner. The steam pressure is 0.1-0.4MPa, and makes the steam trap play a hydrophobic role. You can also increase the tempering temperature accordingly, because the increase in temperature is conducive to the improvement of the maturity of the material. Generally, when the temperature increases by 11°C, the moisture of the material increases by about 1%;
5. The length of the pellets varies, the cutter distance should be adjusted or the deflection scraping position of the material should be adjusted;
6. The position of the two motors with large current deviation should be adjusted to the tension of the belts of the two motors to make the tension as consistent as possible.
Of course, in addition to the above common phenomena and preventive measures, in actual life, we will encounter various situations, all of which are different. Therefore, this requires us to take specific measures for specific situations, so that the feed machinery-feed pellet machine can operate efficiently for a long time, which brings convenience to our work.
