How to reduce the noise when the granulator is working?

The ring die of the co-rotating parallel twin-screw extruder is blocked, or only part of the die hole is discharged. If foreign matter enters the ring die, the ring die is out of round, the gap between the pressing roller and the pressing die is too tight, the pressing roller is worn or the bearing of the pressing roller cannot be rolled, all of which will cause the granulator to vibrate (check or replace the ring die and adjust the gap of the pressing roller). The main shaft is not tightened, especially for D-type or E-type machines. If the main shaft is loose, it will move forward and backward in the axial direction. The pressure roller swings significantly. nut). There may be a problem with the bearing in a certain part of the pellet machine, which makes the machine work abnormally, and the working current will fluctuate. The working current is too high (shut down to check or replace the bearing). The coupling calibration is unbalanced, the concave-convex deviation is left and right, the granulator oscillates, and the gear shaft oil seal is easily damaged (the coupling must be calibrated to the horizontal line).

The large and small gears are worn out, or a single gear is replaced, and there will also be a lot of noise (a running-in time is required). The noise of the twin-screw granulator will not only affect the working efficiency, but also damage the hearing of the operator. 'Noise when the pellet machine is working' is often necessary.
