Some customers encounter pellet mill overheating during pelleting production. The die temperature is high, hot to the touch, and sometimes the machine even stalls. What causes this, and how can it be resolved?
There are several reasons why a pellet machine might overheat, including:
1. Overload operation: The greater the load, the more heat is generated by friction during operation. Increased power consumption easily leads to overheating.
2. Poor bearing lubrication: The root cause of overheating is frictional heat generated by mechanical parts. Poor bearing lubrication leads to increased wear on some parts of the pellet mill, resulting in overheating. Using expired or incompatible lubricating oil can also cause poor equipment operation.
