A detailed Jaw Crusher MONTHLY preventive maintenance Inspection checklist
1. Safety Precautions
2. Visual Inspection
3. Lubrication
4. Jaw Plates
- Examine jaw plates for visible signs of wear.
- Look for uneven surfaces or significant material loss.
- Determine if replacement is necessary based on wear level.
- Document findings and schedule replacement if needed.
- Ensure jaw plates are flush against the frame.
- Verify that no gaps exist between plates and frame.
- Confirm that plates are seated securely in their mounts.
- Adjust if any misalignment is detected.
- Use calipers to measure the gap between jaws.
- Compare measurements against manufacturer specifications.
- Adjust the gap as necessary using shims or spacers.
- Document the gap measurements for future reference.
