Common Jaw Crusher Problems & Fixes
1. Jaw Plates Wearing Out Too Fast
– Cause: Hard or abrasive material, incorrect plate type.
– Fix: Use manganese steel plates for durability; check material feed size.
2. Machine Jamming or Blockages
– Cause: Overfeeding, foreign objects (metal, wood), or wet/sticky material.
– Fix: Use a grizzly screen to remove debris; control feed rate; clear blockages safely.
3. Excessive Vibration/Noise
– Cause: Loose bolts, worn bearings, misaligned components.
– Fix: Tighten all bolts; replace bearings; check foundation stability.
4. Low Crushing Efficiency
– Cause: Wrong speed/throw settings, dull/worn jaws, improper gap adjustment.
– Fix: Adjust CSS (closed-side setting); replace worn parts; optimize RPM.
5. Overheating Bearings
– Cause: Lack of lubrication, overloading, misalignment.
– Fix: Grease bearings regularly; reduce load; align pulleys/belts correctly.

Preventive Maintenance Tips
– Inspect jaws, bearings, and belts daily.
– Lubricate moving parts as per manufacturer guidelines.
– Avoid overloading—use a feeder for consistent material flow.
