Problem & answerB-12
Agitator Not Rotating
Likely causes
- Motor failure
- Loose coupling
- Mechanical obstruction
- Electrical fault
- PLC output failure
How to fix it
- 1Stop and isolate the machine.
- 2Remove any powder obstruction.
- 3Check the agitator motor, couplings and drive.
- 4Verify the PLC output and electrical connections.
- 5Replace damaged components and test rotation before production.
It is fixed when
Agitator rotates smoothly and maintains continuous powder flow.
Stop it coming back
- Inspect the agitator drive weekly; clean the hopper after every batch.
