1. Jaw Crusher Maintenance
Regular maintenance helps prevent unexpected breakdowns and extends the crusher’s lifespan.
Daily Maintenance
- Inspect wear parts (jaw plates, cheek plates) for excessive wear or damage.
- Check lubrication levels (bearings, toggle plate) and top up if necessary.
- Monitor belt tension to prevent slippage or excessive wear.
- Clear debris from the crushing chamber and discharge area.
- Listen for unusual noises (grinding, knocking) that may indicate mechanical issues.
- Grease bearings according to the manufacturer’s recommendations.
- Check hydraulic systems (if applicable) for leaks or pressure issues.
- Inspect fasteners & bolts (toggle plate, jaw dies) for tightness.
- Test safety mechanisms (emergency stops, guards).
- Examine electrical connections for corrosion or loose wires.
- Replace worn-out jaw dies, cheek plates, and toggle plates.
- Inspect the frame for cracks or structural damage.
- Check alignment of the crushing chamber and adjust if needed.
- Lubricate all moving parts thoroughly.
Weekly/Monthly Maintenance
Long-Term Maintenance (Every 6–12 Months)
Common Issues & Solutions
| Problem | Possible Cause | Solution |
|———|————–|———-|
| Excessive vibration | Loose bolts, unbalanced rotor | Tighten bolts, check alignment |
| Overheating bearings | Lack of lubrication, contamination | Re-grease or replace bearings |
| Low production output | Worn jaw dies, improper feed size | Replace dies, adjust feed settings |
| Uneven wear on jaw plates | Misaligned jaws or improper feed distribution | Realign jaws, ensure even feeding |
