How to repair the roller in flat die pellet machine

It would affect the normal production when the roller in the flat die pellet machine wears. Then, how can we repair the roller of the flat die pellet machine apart from the daily maintenance? Generally, there are two kinds of situations, one is severe wear that the roller must be replaced; the other is slight wear and can be repaired.



1. Severe wear
When the roller of flat die pellet machine is badly worn and can no longer be used, it has to be replaced.
2. Slight wear
(1) Check the tightness of the roller, and the roller would wear out when it is too tight. Then, the operator need to loose the roller appropriately.
(2) Check the swing of the main shaft, which must be balanced. It can be effectively solved by adjusting the clearance of the bearing.
(3) Check whether the ring die and roller are matched, and if not, adjust immediately.
(4) Check the material distribution knife of the equipment. The distribution of material would be not uniform If the material distribution knife is broken. It can also lead to the wear of the roller. The material distribution knife can be adjusted or replaced.
(5) Check the feeding knife, adjust the angle and tightness of feeding knife. There should be no sound of friction in the process of making pellets.
(6) Check the raw materials. The materials should not contain any hard objects such as stone or iron, which will not only wear down the roller but also damage the cutting knife. (Get to know how to make wood pellets)
