Why Maintenance Matters
- Bearing failure causes 60% of unscheduled downtime.
- Proper maintenance extends operational life up to 3x.
- Unplanned downtime costs averages $5,000-$15,000/hour in lost capacity.
The Master Schedule
Daily Checks (10 Minutes)
- Visual bolt inspection across the frame.
- Listen for bearing noise.
- Verify amplitude symmetry on all four corners.
- Check spring condition for visible cracks.
- Inspect mesh for damage or severe pegging.
- Monitor motor temperature by touch (carefully) or IR gun.
Weekly Maintenance (30 Minutes)
- Grease bearings (typically 3-5 nipples per shaft).
- Check belt tension.
- Clean drainage channels to prevent water backup.
- Inspect spray nozzles for clogs.
- Verify electrical connections.
- Document operating hours in your log.
Monthly/Quarterly Tasks
- Shaft alignment check.
- Detailed amplitude/frequency measurement.
- Structural fastener torque confirmation.
- Gearbox oil analysis/replacement.
- Motor vibration analysis.
- Screen media wear assessment and thickness measurement.
Bearing Replacement Indicators
Expected bearing life: Usually 6,000-12,000 hours with proper lubrication.
