Solutions to Noises in Wood Pellet Making Machine

When using ring die wood pellet making machine, some users may encounter some noise or sound shocks in the machine and don’t know how to deal with. Here we’d like to specify some tips for new hand.

1. Feed the raw biomass material steadily. Unsteady feed of raw material will cause sound.
2. Check if the spinning scraper is worn and replace new scraper blades in time. Otherwise may cause unsteady feed and generate noise.
3. If the wood pellet making machine is equipped with a new ring die but an old roller or vice versa, it may cause noise. The best is to use both new ring die and roller, and adjust the interval between these two parts.
4. Adjust the composition of raw material and strictly keep its moisture content of 15% to 18%. Otherwise will not make out good pellets.
5. Check if the steam line, system pressure and reducing valve are normal. Otherwise the steam supply will lack pressure.
6. Check if there are impurities inside the pelletizing chamber. If yes, clear them away in time.
7. After used for a long time, the main shaft bearing must have worn. So it should be replaced by a new one.

Above are some possible causes of noise in wood pellet making machine. Hope they will help you in using pellet machine.
