The small granulator is noisy, which not only affects the work efficiency, but also damages the operator's hearing. Therefore, it is very necessary to know how to reduce the noise of the small granulator.
1 The particle machine may have a bearing problem in a certain part, which makes the machine run abnormally and the working current will fluctuate. High operating current (stop inspection or replacement of bearings).
2 ring die blockage, or only part of the die hole discharge. The foreign body enters the ring mold, the ring die is out of round, the gap between the pressure roller and the die is too tight, the roller is worn or the roller bearing is damaged and cannot be rotated, and the granulator vibration is generated (check or replace the ring die and adjust the pressure roller gap).
3 The coupling is unbalanced, there is a deviation between the height and the low, the granulation opportunity has vibration, and the gear shaft oil seal is easy to damage (the coupling must be calibrated to the horizontal line)
4The main shaft is not tightened, especially the D-type or E-type machine. The looseness of the main shaft will cause axial front and rear swaying, the pressure roller will swing obviously, the particle machine will have large noise and vibration, and the granulation will be difficult (the butterfly tail and the round of the spindle tail should be tightened). Nut).
5 large and small gears wear, or replace a single gear, it will also produce high noise (requires running-in time).
6 Unbalanced material discharge at the discharge port of the conditioner will cause large fluctuations in the working current of the granulator (need to adjust the conditioner blade).
7Before using the new ring mold, it is necessary to prepare a new pressure roller, and arrange a certain proportion of sand shovel for grinding, and use after polishing (to prevent the use of inferior ring mold).
8 The tail of the adjuster is not fixed or the fixing is not strong and shakes (requires reinforcement).
