Application
Dust-free Loading in Mineral Terminals
Answer in brief
At a mineral terminal the dust that leaves the loading point leaves the site.
Wind, drop height and fines content decide the plume, and the control has to work in the open rather than in a building.
- Slow the material and keep the outlet near the pile.
- Use suppression where enclosure is impossible.
- Measure at the boundary, not at the chute.

The problem
Open stockpiles and ship loading generate visible dust that crosses the site boundary, and some of it is respirable crystalline silica.
Desired outcome
A loading arrangement that keeps the emission within the permitted limit at the boundary, whatever the wind is doing.
Process approach
Cascade chutes slow the stream and reduce the energy available to loft fines, which is the main control at high rates.
Water or fog suppression is used where enclosure is impractical, with the moisture addition checked against the product specification.
Wind fencing and stockpile management complete the picture, since the loading point is only one source.
- Chute that controls velocity at the outlet.
- Suppression chosen against the product moisture limit.
- Boundary monitoring rather than visual assessment.
Selection factors
- Fines fraction and its respirable content.
- Loading rate and drop height.
- Permitted moisture addition to the product.
- Prevailing wind and boundary distances.
- Emission limits and the monitoring method.
Common failure modes
- Water suppression pushing the product over its moisture limit
- Outlet left high above the hold as it fills
- Emission judged visually rather than measured
- Stockpile treated separately from the loading point
