Dust prevention
Raises moisture in material before dust becomes airborne — pre-wetting and binders that reduce particle liberation at crushers, feeders, and transfer points.
Dust Suppression & Compliance
Prevention and suppression systems engineered for mining circuits, haul roads, and underground airways.
Dust management
Prevention and suppression work best together
Airborne respirable dust presents critical health risks and severe mechanical wear. The most effective programmes combine dust prevention at source with suppression of particles already in the air — sized to your circuit, water availability, and statutory dust limits.
Sites that only wet material — or only knock down airborne clouds — often leave gaps. We design programmes that do both: keep fines locked in the ore stream, and capture what still escapes into the air.
Dust suppression
Knocks down dust already airborne with target-matched spray or fog so particles collide, agglomerate, and fall out of the air stream.
Results you can see
Drag to clear the dust
Pull the handle across each scene — the same before/after principle used on ROM bins and crushing circuits once misting and source wetting are applied.
ROM bin tip dust under control
Uncontrolled tipping throws a dense dust plume across the hopper and adjacent walkways. Source wetting plus mist curtains capture fines at the drop point and restore usable visibility around the tip.
Transfer-point fogging on the crushing circuit
Chute discharges and belt transfers are classic fugitive-dust generators. Matched fog nozzles agglomerate airborne particles so they fall out of the airstream without flooding the ore stream.
Why it matters
Control dust before it controls your operation
Falling productivity, climbing maintenance bills, and rising health exposure are classic early warnings that fugitive dust is winning.
Health
Breathing fine mine dust over time is tied to serious lung disease. Silica, coal dust, and other particulates remain among the highest occupational risks on site.
Safety
Dust clouds cut visibility around tip points, haul roads, and plant floors — raising the chance of vehicle and pedestrian incidents.
Legislation
When ambient dust stays above allowed limits, mines face audit findings, fines, and in severe cases production stoppages or personal liability for managers.
Downtime
Dust is a major driver of abrasive wear and fouling. Industry analyses often link a large share of plant failures and rising maintenance spend to uncontrolled dust.
Dust & disease pathways
Different dusts, different health stakes
Mining and plant dust is not one problem. Particle chemistry changes the medical risk — which is why source control matters across silica-rich ore, coal, and diesel-heavy zones.
Silica dust
Silicosis, tuberculosis risk, COPD, lung cancer
Coal dust
Coal workers’ pneumoconiosis (black lung), COPD
Metal / process dusts
Metal-specific toxicity (e.g. lead, manganese, nickel, cadmium pathways)
Diesel particulate
Respiratory and cardiovascular burden in confined or poorly ventilated areas
How we approach it
Site-specific control, not a one-size kit
Source capture on plant
Spray and fog packages at ROM bins, crushers, screens, and transfer points keep dust from entering the air in the first place.
Pressure matched to the duty
Medium- and high-pressure systems, and where needed cannon-style coverage, are selected against particle size, airflow, and water availability.
Haul roads & open areas
Binders and water-efficient suppressants stabilize fines on primary, secondary, and access roads, stockpiles, and exposed dumps.
Automation where it pays
Solenoid and pump control — and on larger plants SCADA-friendly packages — keep spray on only when material is moving, cutting waste and downtime.
Typical applications
Where dust control belongs on a mining circuit
Spreading control from the ROM bin through crushers, screens, and transfers lowers overall dust load so no single hotspot has to carry the whole burden.
Primary dump hoppers / ROM bins
Jaw, cone, and gyratory crushers
Vibrating screens
Conveyor transfer points
Stackers and reclaimers
Stockpiles and tip areas
Haul roads and transport corridors
Coal and ore loading terminals
Feeder to belt / hopper / impactors
Mine shafts and ventilation areas
Continuous miners and shearers
Trucks and mobile loading points
Crushing circuit focus
Key points that generate the most dust
Loading / ROM bins, feeders, grizzlies, crushers, screen feed and discharge, conveyor transfers, chutes, and head-chute discharges typically need matched prevention and suppression.

Compliance
Built around statutory dust limits
Our systems enable mine operators to maintain ambient dust levels well below statutory maximum allowable concentrations (MAC). By capturing dust particles at the source through target-matched fog and mist droplets, we help management ensure continuous compliance during regulatory audits while protecting worker safety.
Every installation is sized around particulate density, airway geometry, water availability, and production rates — so suppression works without over-wetting ore or creating secondary hazards.
