Application
Dust Collection in Grain and Feed Plants
Answer in brief
In grain handling the dust collection system is the primary explosion control, because it removes the fuel before it settles.
Aspiration at the intake pit, the elevator boot and the conveyor heads captures dust where it is generated.
- Aspirate at each generation point, not from the building.
- Protect and isolate the filter.
- Decide what happens to the recovered dust.

The problem
Grain dust is combustible and generated at every transfer; what is not captured settles on structures and becomes the secondary explosion fuel.
Desired outcome
An aspiration system that captures dust at each point of generation, with a protected filter and a defined route for the recovered material.
Process approach
Aspiration volumes are calculated per point rather than estimated, because an undersized hood captures nothing and an oversized one carries product away.
The filter is protected, isolated and located with its discharge route in mind, since recovered dust is usually blended back into feed or disposed of.
Housekeeping remains part of the concept; collection reduces the layer but does not remove it.
- Aspiration volume per capture point.
- Protected and isolated filter.
- Defined route for recovered dust.
Selection factors
- Number and type of capture points.
- Air volume and duct velocities to keep dust moving.
- Explosion characteristics of the collected dust.
- Use or disposal route for recovered material.
- Housekeeping method and interval.
Common failure modes
- Hood sized by eye rather than by calculation
- Duct velocity too low, letting dust settle in the duct
- Filter unprotected and unisolated
- Recovered dust returned without considering its composition
