Silo Dust Collector Commissioning Checklist
Mechanical, electrical, pulse-system and loaded commissioning checks before normal silo filling begins.
Technical review updated 2026-06-20Commissioning proves that the installed collector, utilities, controls and silo protection system work together under real filling conditions. A dry electrical test alone is not enough.
Mechanical Inspection
- Mounting bolts, gasket and flange sealing
- Filter seating, cages and clean chamber
- Blow-pipe alignment and valve supports
- Fan guards, rotation clearance and duct supports
- Access doors, weather hood and drainage
- Safe platform, lifting points and housekeeping
Utilities and Controls
Confirm voltage, phase, earthing, motor overload settings and disconnect operation. Check compressed-air cleanliness, regulator setting, isolation and drain.
Simulate high differential pressure, high silo level, fan fault and other required interlocks. Verify that the conveying system stops safely when a critical permissive is lost.
Functional Test
Jog the fan and confirm direction. Run the complete pulse sequence and identify each valve. Measure header pressure before and during pulsing. Check instrument zero and impulse lines.
Record clean differential pressure at known airflow and controller settings.
Loaded Test and Handover
Observe the fastest normal filling cycle. Watch silo pressure, differential pressure, outlet emissions, fan current and pulse recovery. Confirm relief devices do not activate during normal operation.
Handover approved drawings, settings, manuals, spare parts and training records. Define the first inspection after initial operation.
Project Checklist
- Complete safety review
- Inspect mechanical installation
- Test electrical and air utilities
- Prove interlocks
- Record baseline
- Run loaded test
- Issue commissioning report
Engineering note: Commissioning should be led by competent personnel with authority to stop filling if pressure or emissions become abnormal.
