Stone crushing lines play a vital role in mining and construction industries, producing aggregates essential for infrastructure projects. To maintain optimal performance and prevent unexpected downtime, daily inspections must be carried out systematically. Here’s a structured guide for inspecting key components of a stone crushing line.

1. Vibrating Feeder

  • Check for abnormal vibrations or uneven feeding.
  • Ensure proper alignment and tightening of bolts/supports.
  • Inspect springs or shock absorbers for wear or damage.

2. Jaw Crusher / Primary Crusher

  • Monitor feed size consistency to avoid overload.
  • Verify lubrication oil level and cleanliness.
  • Check wear parts (jaw plates, liners) for excessive wear or cracks.
  • Listen for unusual noises indicating mechanical issues.

3. Cone Crusher / Impact Crusher (Secondary Crushing Stage)

  • Examine hydraulic system pressure/vibrations for irregularities.
  • Inspect cone liners or impact bars for wear-related inefficiencies.
  • Confirm belt tension/pulley alignment (if applicable).
  • Check lubrication system filters for contamination.

4. Vibrating Screen

  • Ensure screen cloths/mesh are intact without tears or blockages.
  • Inspect vibration motors for overheating or abnormal noise.
  • Verify proper tension in springs and support structures.

5. Conveyor Belts

  • Look for misalignment, tears, or belt slippage.
  • Confirm roller and pulley lubrication.
  • Clear accumulated debris to prevent belt wear.

6. Dust Control & Electrical Systems

  • Ensure dust suppression nozzles are unclogged and functioning.
  • Inspect electrical panels/wiring for wear or moisture ingress.
  • Verify emergency stop functions are operational.

Additional Checks:

  • Daily: Lubrication levels, unusual noises, belt/pulley status.
  • Weekly: Gearbox oil contamination, motor alignment, foundational bolts.
  • Post-Maintenance: Conduct test runs after component replacements to ensure balance and synchronization.

A well-maintained stone crushing line ensures uninterrupted production, prolongs equipment lifespan, and improves safety. Implementing a structured daily inspection routine minimizes breakdowns and maximizes operational efficiency.
