As stated earlier in the guide setting the biomass pellet machinery so a carpet forms over the die can reduce the percentage of fines by up to 30%.
Biomass Pellet Machinery-Grade Sieving
After pellet production, pellets can be run over a vibrating screen to remove fines. However if the biomass pellet machinery is setup properly and the material is properly compressed this may not be required. However it must be remembered that making sure that the pellets are mechanically strong is the most important thing, as this will reduce fines after production.
