For uneven pellet length in the pellet mill, adjust the cutter distance or material distribution deflector position.
If pellets from the pellet mill are smooth but excessively hard, the issue may stem from a high die compression ratio – reduce the ratio accordingly.
For rough pellet surfaces and high powdering rate in the pellet mill, the die compression ratio may be too low – increase the die hole compression.
If the pellet mill encounters high material moisture (leading to low output and frequent blockages), raise the conditioning temperature – higher temperature enhances material gelatinization.
For axial/radial cracks, high powdering rate, and low output in the pellet mill, the cutter may be dull or positioned too far (pellets are broken/teared instead of cut) – sharpen or reposition the cutter.
