1. Overview of Mining Machinery Equipment
Mining machinery equipment serves as the core asset in mining operations, encompassing extraction equipment (such as roadheaders and rock drills), mineral processing equipment (like crushers and screening machines), as well as auxiliary systems including lifting, conveying, ventilation, and drainage. The reliable performance of these systems is crucial for operational efficiency and safety.

2. Maintenance Tips for Mining Machinery Equipment
Scientific maintenance is key to extending equipment lifespan and ensuring productivity. Haphazard maintenance not only increases workload but may also lead to adverse outcomes.
Key maintenance techniques include:

2.1. Collision Prevention and Cleaning
Avoid external impacts to prevent structural deformation or component damage.
Regularly remove dust, grease, and debris from surfaces and internal parts, and prevent contact with corrosive chemicals.

2.2. Bearing Lubrication Management
Bearings are the core load-bearing components, and their lubrication status directly affects service life and operational efficiency.
Use clean lubricants and ensure proper sealing to prevent contamination.
Key lubrication points include: rotating bearings, roller bearings, gear sets, movable bearings, and sliding surfaces.

2.3. Regular Inspection and Documentation
Maintain equipment inspection logs to record daily operation status, maintenance history, and part replacements.
Utilize data analysis to predict potential failures and address issues proactively.

2.4. Environmental Adaptability Management
Equipment performance is significantly influenced by environmental factors such as humidity, dust, and temperature. Strengthen monitoring and protective measures accordingly.

3. Key Maintenance Components and Operational Guidelines
3.1. Bearing Systems: Regularly check lubrication status; immediately shut down and investigate if abnormal temperature rise occurs.
3.2. Fastener Inspection: Newly installed parts (like tire rings) are prone to loosening and require frequent checks and tightening.
3.3. Wear Parts Monitoring: Periodically assess the wear level of vulnerable parts such as gears and liners, and replace them in a timely manner.
3.4. Movable Assembly Maintenance: Clean debris from the chassis plane to ensure smooth movement of movable bearings and prevent jamming accidents.
3.5. Abnormal Noise Handling: If impact noises from gears or other transmission components are detected during operation, stop immediately for inspection.

Conclusion
Maintenance of mining machinery should be prevention-oriented. Through standardized operations, refined management, and scientific diagnostics, failure rates can be minimized, ensuring both safety and efficiency. Maintenance should not be limited to repairs but integrated throughout the equipment's entire lifecycle.
