1. Poor fluidity of granular materials: granular materials may accumulate in the silo of the feeder, or be blocked or stuck during transportation, resulting in the inability of materials to flow or return.
2. Oil bath rod path failure: The oil bath rod feeder is a conventional granular material conveying equipment, and its internal path and transmission system may fail or be damaged, resulting in poor material flow or failure to return materials.
The specific circumstances and causes of the problem need to be analyzed in detail. If you can't handle it yourself, you need to find professional technicians to check and repair it.
