Dust control and industrial spray
Dust Control & Industrial Spray
Dry fog, mist, sprinkler and fog cannon systems, wind fences and industrial spray nozzles for controlling dust at transfer points, crushers, stockyards and unloading areas, engineered from the dust source and site constraints.
Typical challenges
Where customers usually start
- Visible dust at conveyor transfer points, chutes and hoppers
- Dust at crusher and screen discharge
- Wind-blown dust from stockpiles and open yards
- Dust during wagon, truck or ship unloading
- Materials or processes that cannot accept added moisture
- Blocked nozzles and spray systems that are hard to maintain
Start with the dust source, not the equipment
Dust control works best when it is designed around where and why dust is released. Fine particles escape when material falls, impacts and displaces air at a transfer point, when it is broken in a crusher, when wind strips the surface of a stockpile, or when vehicles disturb dry ground. Each situation calls for a different approach: suppressing airborne dust with very fine droplets, wetting the material before it moves, reducing wind speed across an open yard, or containing the source so there is less air movement to begin with.
This capability brings together dry fog and mist systems, wet sprinkler and stockyard spray systems, fixed and mobile fog cannons, wind fences, truck wash systems and the nozzles, pumps, filters, manifolds and controls behind them, along with site survey, installation and maintenance services. Mechanical measures such as better chute sealing, skirting and settling zones are considered alongside suppression, because reducing the amount of dust released makes any suppression system easier to apply.
Constraints that shape the design
The same transfer point can need a very different solution depending on the material handled, its throughput, how well the source is enclosed and how much moisture the material can tolerate. Utilities are equally important: water quality and availability, compressed air and electrical power at the location all limit what is practical. For larger or open areas, prevailing wind, layout and access for maintenance come into play. Our dust-control discovery journey collects these inputs and produces a brief for engineering review, so that unknowns are visible before any equipment is proposed.

Frequently asked questions
What is the difference between dry fog and water spray dust suppression?
Water spray wets the bulk material so that fines stick to larger particles and are less likely to become airborne. Dry fog uses very fine droplets, usually produced with compressed air, to capture dust that is already airborne inside an enclosed space while adding little moisture to the material. Which one fits depends on the dust source, the enclosure and the moisture the material can accept.
What information is needed to start a dust-control enquiry?
Useful starting points are the dust source, the material and its throughput, how enclosed the source is, any limit on added moisture, and whether water, compressed air and power are available nearby. Layout drawings or photographs help considerably. Unknown items can be left open and confirmed during review or a site study.
Do dust-control systems need regular maintenance?
Yes. Nozzles, filters and strainers need periodic inspection and cleaning, particularly where water quality is poor, and pumps, compressors and controls need routine checks. Planning access for maintenance at the design stage makes it easier to keep a system working as intended.
