Analysis on the cause of large vibration of biomass granulator

1. There may be a bearing problem in a certain part of the biomass pellet machine, which makes the machine run abnormally, and the working current will fluctuate. The working current is too high (shut down to check or replace the bearing).
2. The ring die of the biomass pellet machine is blocked, or only part of the die hole is discharged. 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 rotated, all of which will cause a vibration of the pellet machine (check or replace the ring die, and adjust the gap between the pressing rollers).
3. The coupling of the biomass pellet machine is unbalanced, there is a deviation between the height and the left and right, the pellet machine will vibrate, and the oil seal of the gear shaft is easily damaged (the coupling must be calibrated to the horizontal line)
4. The main shaft of the biomass pellet machine is not tightened, and the loosening of the main shaft will cause the axial movement back and forth, the pressure roller swings obviously, the pellet machine has a lot of noise and vibration, and it is difficult to make pellets (the butterfly spring and round nut at the end of the main shaft need to be tightened).
5. Strictly control the tempering time and temperature, and keep abreast of the water content of the raw materials entering the machine. If the raw materials are too dry or too wet, the discharge will be abnormal and the pellet machine will work abnormally.
6. The tail of the conditioner of the biomass pellet machine is not fixed or is not firmly fixed, resulting in shaking (requires reinforcement)
