Joining us on this episode of Wiki Bearings is Safdar Hashimi, a seasoned maintenance engineer at Al Jaber Crushers & Quarries, who provides valuable insights into the technical aspects of crusher operations and maintenance (maintenance, repair, and overhaul (MRO) challenges).

Key MRO Challenges in the Crusher Industry

1. Frequent Breakdowns: Crushers are subjected to extreme stress, making breakdowns a common issue. Regular inspections and timely maintenance are critical to minimize downtime.
2. Wear and Tear of Parts: The abrasive nature of materials processed by crushers leads to significant wear and tear. Replacing wear plates, screen meshes, and other components is a routine but essential task to maintain efficiency.
3. Difficulty in Sourcing Spare Parts: Ensuring a steady supply of high-quality spare parts is a major challenge. Delays in sourcing parts can lead to extended downtime and reduced productivity.
4. High Maintenance Costs: The cost of maintaining crushers can be substantial, covering everything from spare parts to labour. Efficient maintenance practices and cost-effective sourcing are vital to managing expenses.

Lubrication and Bearing Maintenance

Lubrication is a critical aspect of crusher maintenance. Proper lubrication reduces friction, wear, and overheating, thereby extending the lifespan of bearings and other components. For example, it is recommended to change the lubrication of cone crushers every 2,000 hours, whereas screen lubrication is required every 500 hours due to constant vibration.

Optimizing Crusher Performance

To optimize crusher performance, it is crucial to follow manufacturer guidelines and implement preventive maintenance strategies. Regular monitoring of key components such as bearings, belts, chains, and seals helps in identifying potential issues before they lead to significant problems. Using advanced diagnostic tools can further enhance the ability to maintain optimal performance.
