A: There are several reasons to this situation:

1. The conveying speed of raw material is not stable. You should adjust the feeding speed.
2. The deflection scraper is wearing out making the feeding speed fluctuation. You should replace it with a new one.
3. Among the ring die and the roller, one is new and the other is old. This combination should be avoided. It is better to use new ring die with new roller.
4. The distance between the ring die and roller doesn’t match with the raw material. Try to adjust the distance and make the machine running smoothly.
5. The roller of the pellet machine is wearing out.
6. The raw material is difficult to be pelletized. Make some appropriate adjustments to the material.
7. The steam supply is insufficient or the pressure is waving. Check the steam pipe, pressure system and reducing valve. Make sure they are normal.
8. Impurities are mixed into the machine chamber.
9. The spindle bearing is wearing out or damaged and needs to be replaced.
