Automatic Pellet Feed Production Machine

If the middle part of the roller is larger and the two ends are smaller, this is usually caused by uneven feeding or the same pair of rollers being used on the same ring die for too long. In order to solve this problem, we should take the method of using multiple roller assemblies in turn, because the roller wears faster, while the ring die wears slower. This is conducive to the normal wear between the ring die and the roller, making the working surfaces of both sides relatively flat, which is conducive to production.

In addition, if the working surface of the roller is not worn properly, it is usually caused by the roller edge, uneven feeding or too tight gap between the die rollers. If there are protruding parts on the two ends, they should be ground off all around; if the top of the roller teeth is deformed, it can be repaired with a grinding wheel; if there are foreign objects in the middle of the tooth groove, such as iron blocks, they should be removed.
In summary, the maintenance and care of the roller is an important task, which requires us to pay attention to the size of the roller, the wear of the working surface, the bearing clearance and other aspects.
