procedures for operating mobile crusher

Operating a mobile crusher safely and efficiently requires adherence to specific procedures to ensure both equipment longevity and personnel safety. Below are the key steps:

1. Pre-Operation Checks

• Inspect the Crusher:

– Check for wear/damage on jaws, liners, hammers, or cones.
– Ensure belts, chains, and conveyors are properly tensioned.
– Verify hydraulic lines and fittings for leaks.

• Check Fluid Levels:

– Engine oil, hydraulic fluid, coolant, and fuel levels should be adequate.

• Examine Safety Features:

– Emergency stops, guards, and warning alarms must be functional.

• Clear Debris: Remove any obstructions around the crusher.

2. Start-Up Procedures

• Position Correctly: Ensure the crusher is on stable ground with proper clearance.
• Engage Safety Protocols: Wear PPE (hard hat, gloves, safety glasses, hearing protection).
• Power Up: Follow manufacturer guidelines for starting (electric/diesel). Allow warm-up time if required.



3. Operating Procedures

• Feed Material Properly:

– Avoid overloading; use a controlled feed rate (e.g., via excavator or loader).
– Remove oversized or uncrushable material (metal, wood) beforehand.

• Monitor Performance: Watch for unusual noises, vibrations, or blockages. Adjust settings as needed (CSS gap for jaw/cone crushers).
• Avoid Contamination: Prevent non-crushable materials from entering the crushing chamber.

4. Shutdown Procedures

• Empty the Chamber: Let all material pass through before stopping.
• Turn Off Power Sequentially: Follow manufacturer shutdown steps (e.g., idle engine before turning off).
• Lock Out/Tag Out (LOTO): If servicing is needed.



5. Maintenance & Post-Operation

• Daily: Lubricate bearings/grease points; inspect wear parts; clean dust/debris.
• Weekly/Monthly: Check belt alignment, tighten bolts/nuts, replace worn components per schedule.
