How to extend the service life of vibrating screen
To extend the service life of your vibrating screen and ensure efficient operation, a consistent and thorough maintenance program is essential.
How to extend the service life of vibrating screen
1. Regular Inspection
Frequency: Daily, weekly, and monthly inspections are crucial.
What to check:
Screen Media: Look for tears, holes, wear, proper tension, and cleanliness. Ensure it’s correctly installed and that gaskets (if required) are in place.
Structural Components: Examine the frame, supports, and cross beams for cracks, fatigue, or damage.
Fasteners: Regularly check and tighten all bolts, nuts, and other fasteners, especially on screen panels, clamping systems, and motor mounts. Re-tighten bolts after the initial 7 hours of work.
Springs: Inspect for wear, damage, and proper compression. Measure springs against OEM tolerances and replace as a complete set if out of tolerance.
Crown Bars: Ensure proper and continuous crown on all decks. Repair or replace according to the manufacturer’s guidelines.
Drive System: Inspect V-belts for wear, damage, and proper tension. Check for leaks in the drive system.
Mounting System: Ensure the machine is securely mounted and free from damage.
Safety Guards: Confirm they are firmly in place and not compromised.
Why: Early detection of issues prevents more significant damage and downtime.
2. Proper Lubrication
Frequency: Follow the manufacturer’s recommendations for lubrication intervals. Daily lubrication of drive bearings and ensuring grease lines are intact is often necessary.
What to do:
Lubricate bearings, drive mechanisms, and other moving parts with the recommended lubricant and quantities.
Inspect grease lines for leaks or blockages.
For central lubrication systems, perform thorough inspections weekly.
Monitor bearing temperature; overheating can indicate lubrication issues.
Why: Reduces friction and wear, preventing premature failure of moving parts.
3. Screen Cleaning
Frequency: Clean the screen surface regularly, the frequency depends on the material being screened. Daily cleaning is often necessary.
How to do it: Use a brush, air blower, or water spray (depending on the material and screen media) to remove buildup of material, debris, or blockages.
Why: Maintains efficient screening performance and prevents excess weight and strain on the screen.
