If you suddenly notice a sudden increase in noise from the pellet mill equipment during the production process, you need to pay attention immediately, as this may be caused by operating methods or internal reasons of the equipment. It is necessary to promptly eliminate potential problems to avoid affecting subsequent normal production.
There are several factors that contribute to the high noise of the pellet mill, which can be compared and addressed.
1. Ring mold blockage, out of roundness, only partial discharge; The gap between the pressure roller ring mold is too small or damaged, which prevents it from rotating. (Check or replace the ring mold, adjust the gap between the pressure rollers).
2. The bearing has a problem and the equipment is not running properly, resulting in a high operating current. (Replacing bearings)
3. The coupling is unbalanced and there is a deviation in the left and right heights, which makes it easy to damage the gear shaft oil seal. (Balance correction coupling)
4. The uneven discharge of the modulator's discharge port leads to increased current fluctuations in the pellet mill. (Adjust the modulator blades and evenly discharge the material)
5. The spindle is loose, causing the production process to move back and forth, resulting in significant swinging of the pressure roller and significant noise during granulation. (Tighten the spindle)
6. Before using the new ring molding roller, it needs to be ground and polished before use. (Eliminate low-quality ring molds)
7. Wear of large and small gears, or replacement of gears, can also produce increased noise. (Need to run in for a period of time)
8. Scientifically control the tempering time and temperature. Materials that are too dry or too wet can cause abnormal granulation.
9. The chassis and steel frame structure of the pellet mill are not firm and are prone to vibration. (Strengthen the structure and select high-quality granulation equipment)
10. The tail of the modulator is not securely fixed or loose. (Check reinforcement)
