Abnormal Noise Maintenance Method of Quiet Granulator

Let’s share with you Quiet granulator has abnormal noise maintenance method:

　　1. The Quiet granulator may have a bearing problem in a certain part, which makes the machine work abnormally and the working current will fluctuate. The operating current is too high (stop to check or replace the bearing).

　　Second, the ring die 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 pressure roller and the pressure die is too tight, the pressure roller is worn or the pressure roller bearing is damaged and cannot roll, the granulator will vibrate (check or replace the ring die, adjust the gap of the pressure roller).

　　3. The coupling calibration is unbalanced, the unevenness is deviated from the left and the right, the granulator may oscillate, and the gear shaft oil seal is easily damaged (the coupling must be calibrated to the horizontal line).

　　4. The main shaft is not tightened, especially for D or E type machines. If the main shaft is loose, it will move back and forth in the axial direction, the pressure roller swings significantly, the noise of the pellet machine is large, and it is difficult to make pellets (it is necessary to tighten the butterfly spring of the spindle tail And round nuts).

　　5. The large and small gears are worn out, or if a single gear is replaced, noise will also occur (a running-in time is required)
