Biomass Pellet Machine (Ring Die) Core Wear Parts List and Maintenance Key Points
In biomass pellet production, the efficient operation of a ring die pellet machine depends on the condition of key wear parts. The following is a list of parts that require regular inspection and replacement, which directly impacts equipment lifespan and production costs:
Ring Die (Core Component)
Function: The key die for material forming, determining pellet density and output.
Damage Signs: Die hole wear (exceeding 10% of the designed aperture) and surface cracks.
Press Roller Assembly
Components: Press Roller Shell, Bearings, and Seal Rings.
Causes of Damage: High-temperature wear caused by friction with the ring die, scratches caused by raw material impurities.
Seal Ring
Function: Prevents material leakage and protects bearings.
Consequences of Failure: Dust intrusion can cause bearing seizure and reduced pellet forming efficiency.
Spindle Bearing
High-Risk Scenarios: Seal failure or insufficient lubrication can easily cause burnout.
Conclusion
80% of ring die pellet machine failures are due to wear part failure! Establishing regular replacement files and selecting wear-resistant accessories can reduce per-ton production capacity by more than 15%.
