The ring die of the pellet machine affects the pellet making in the following aspects:
1. Die hole length: The longer the material is extruded in the die hole, the harder the finished pellets are and the better the strength is. On the contrary, the pellets will be loose and the powdering rate will be high.
2. Die hole flatness: The lower the pore roughness, the smoother the pellets produced. Easy to extrude and mold, not easy to crack, and the pellet quality is good.
