1. Daily Maintenance
– Inspect the machine visually for cracks, wear, or loose parts.
– Check oil levels (engine, hydraulic, and lubrication systems).
– Monitor belts and pulleys for wear, tension, and alignment.
– Clear debris from the crushing chamber and discharge area.

n for unusual noises (grinding, knocking) during operation.
2. Weekly/Monthly Maintenance
– Lubricate bearings and moving parts (follow manufacturer guidelines).
– Inspect jaw plates, liners, and blow bars for wear; replace if worn beyond tolerance.
– Check hydraulic systems for leaks or pressure drops.
– Tighten bolts and fasteners, especially on vibrating components.
– Clean air filters and cooling systems to prevent overheating.
3. Quarterly/Annual Maintenance
– Replace worn-out parts (bearings, seals, conveyor belts).
– Check electrical components (wiring, switches, motors).
– Test safety features (emergency stops, guards).
– Perform alignment checks on crusher jaws or cones.
– Schedule professional inspection by a technician.
4. Operational Best Practices
– Avoid overloading the crusher to prevent premature wear.
– Feed material evenly to reduce uneven wear on components.
– Use proper-sized material to avoid jamming or excessive strain.
5. Common Issues & Fixes
| Issue | Possible Cause | Solution |
|——-|—————|———-|
| Excessive vibration | Loose bolts/unbalanced rotor | Tighten bolts/balance rotor |
| Reduced output | Worn liners/jaws | Replace liners/jaws |
| Overheating | Low oil/clogged filters | Refill oil/clean filters |
| Strange noises | Bearing failure/misalignment | Replace bearings/realign |
6. Safety Considerations
– Always shut off power before performing maintenance.
– Use lockout/tagout (LOTO) procedures when servicing.
– Wear PPE (gloves, goggles, hard hat).
By following this maintenance routine, you can extend the lifespan of your gravel crusher and minimize downtime. Always refer to the manufacturer’s manual for model-specific guidelines.
