Heavy process equipment such as kilns, grinding mills and their fans give early warnings through vibration, bearing temperature and power draw well before they trip.
Common problems
Rising vibration
Trend vibration with load and speed to separate process changes from mechanical wear.
Bearing temperature alarms
Compare bearing temperatures with ambient, lubrication intervals and load.
Power draw changing
Track specific power (kWh per tonne) to see whether efficiency is drifting.
Evidence that helps
- Vibration and temperature trends
- Motor current or power data
- Maintenance log
Work on burners, fuel trains, pressure vessels and electrical equipment must be carried out by qualified personnel following the manufacturer's instructions and local codes. Never bypass a flame safeguard, limit or interlock.
