Strange Pellets Discharged From Sawdust Pellet Mill

The first kind of pellet is not straight and has many cracks on surface. This kind of pellet will appear when materials leave the ring die. Near the discharging mouth, there is a cutting blade. If the cutting blade is a little far from the ring die or blunt, pellets will be fractured. At this time, some pellets become concave and have cracks on surface.

During the cooling or delivering process, these cracked pellets will be hit again and become powders. To solve this failure, there are four ways. At first, we can increase the compression ratio of ring die to strengthen the raw materials. Sometimes, we may add the molasses or fat in raw materials.

To increase the hardness of raw materials, we should strictly control the adding amount of these materials. The third way is to adjust the distance between cutting blade and ring die. Usually, the distance should be smaller than the pellet diameter. Besides, we can use the relatively sharp cutting blade. At last, to increase the adhesive force between raw materials, we can use the adhesives.
