Reason: This situation is often the pellet material leaving the machine is produced, when the cutter position is adjusted far from the surface and the knife is blunt, the particles from the die hole extrusion is cut by the knife touch or tear rather than be cut off, then some of the pellet material curved to one side and the other side shows many cracks. This kind of granular material in the cooler into the cooling or transportation process, often from these cracks will break, resulting in the production of granular material powder too much.
Improvements:1、Increase the compression ratio of the mold, so as to increase the density and hardness value of the pellet material.
2、Crush the raw materials more finely to improve the density of the pellet material and prevent the feed from being flimsy.
3、Adjust the distance between the surface of the cutter and the mold or replace the cutter with a sharper one.
