With the continuous development of industrial production, pellet machines have been widely used in fields such as pellet fuels, fertilizers, and feed as an important mechanical equipment. However, due to long-term use, the pellet machine’s grinding tools are prone to wear and require timely repair and replacement; otherwise, it will affect the production efficiency and product quality of the pellet machine.
There are several methods to repair the worn-out grinding tools of pellet machines:
1.Welding repair method. The severely worn-out grinding tools of the pellet machine are cut and cleaned, and then locally heated for repair using welding technology. However, this method is prone to deformation and cracking of the tools, which will affect the production efficiency and stability of the pellet machine.
2.Film replacement repair method. This method involves polishing the worn-out grinding tools of the pellet machine and then coating them with special coatings to form a film. However, the repair effect of this method is difficult to guarantee, and the coatings need to be replaced regularly, making it a costly method.
3.Adhesive repair method. This method involves polishing the worn-out grinding tools of the pellet machine and then using special adhesives for repair. This method can repair small areas of wear, but its effect is not ideal for large areas of wear.
4.Powder spraying repair method. This method involves spraying special alloy powders on the surface of the grinding tools for repair. This method can effectively repair the wear of the tools, has a relatively low cost, and can improve the service life and production efficiency of the pellet machine.
It should be noted that regardless of the repair method used, it needs to be tested and repaired by professional technicians. During the use of the pellet machine, it is also necessary to regularly inspect and maintain the grinding tools, identify and solve problems promptly, to ensure the normal operation and production efficiency of the pellet machine.
