Why the wood pellets are bent and many cracks appear on one side?
These phenomena are caused when the pellet leaves from the wood pellet machine ring die. When the cutter position is far away from the rig die surface and the cutter edge is too blunt, the pellet is broken by touching or tore but not by cutting, at this time, some pellet bends one side and the other side surface appears cracks.
Increase the pressure from the ring die to the feed, which is to increasing the compression ratio of the ring die, thus increasing the density and hardness of the pellet material; crush the feed raw materials much finer, if the molasses or fat is added into it, the dispersion uniformity should be improved and the additive amount should be controlled, to improve the pellet density, avoiding feed being loose; adjust the distance of the cutter from the surface of the ring mold or replace it with a sharper cutting blade; use aid additive with bonding, to improve the inner binding force of the pellet.
