For a high-performance Hydraulic Roller Crusher, the hydraulic system is the “brain” and the “muscle.” It not only provides the necessary crushing pressure for hard materials like granite and quartz but also acts as the primary safety mechanism against tramp iron.
Proper Hydraulic Roller Crusher maintenance is the difference between a machine that lasts 10 years and one that fails in two.

1. Monitoring System Pressure
The core of hydraulic efficiency lies in pressure stability.
-
Optimal Range: Always operate within the factory-recommended pressure parameters. Over-pressuring can lead to seal failure, while under-pressuring results in oversized output.
-
Check for Leaks: Even a minor “sweat” at a hose fitting can lead to system contamination. Tighten connections immediately.
2. Hydraulic Oil: The Lifeblood of the System
In the context of Hydraulic Roller Crusher maintenance, oil quality is non-negotiable.
-
Viscosity: Use the correct grade of anti-wear hydraulic oil based on your local ambient temperature.
-
Filtration: Replace filters every 500 operating hours. Contaminated oil is the #1 cause of valve blockage.

3. Automatic Overload Protection (Tramp Iron Relief)
One of the biggest advantages of our hydraulic system is the safety bypass.
-
How it works: When an unbreakable object (like a loader tooth) enters the crushing chamber, the hydraulic pressure spikes, causing the cylinders to retract instantly.
-
Maintenance Tip: Regularly test the accumulator’s nitrogen pre-charge pressure to ensure the “rebound” effect is snappy and protective.
4. Common Troubleshooting Checklist
| Symptom | Potential Cause | Solution |
| Pressure Drop | Worn Seals or Leak | Replace Seal Kit / Tighten Fittings |
| Erratic Roller Movement | Air in Hydraulic Lines | Bleed the system via the relief valve |
| High Oil Temperature | Clogged Cooler / Low Oil Level | Clean the radiator / Top up oil |
Conclusion
A well-maintained hydraulic system ensures consistent product size and protects your rollers from catastrophic damage. By following this Hydraulic Roller Crusher maintenance routine, you ensure your plant runs at maximum uptime.
