Dust suppression for Australian mines and quarries

Fix the source, save the water

Every litre that evaporates uselessly is a litre that had to be carted. Source control is the same engineering everywhere, and it is where the saving is:

• Lances and ring manifolds at crusher discharges, transfer points and screen decks.
• Zone control so only the working area is sprayed — a plant that sprays the whole yard all day is spending water on empty space.
• Dust, wind or activity triggers, which stop the system when the material stream stops.
• Filtration (5 μm) designed for the site water, because blocked nozzles on a remote site mean a long trip.

Designed for remote maintenance

On a remote site, the maintenance interval is a cost multiplier, so we specify for it: sealed, easily cleaned filter housings; stainless nozzles with ruby orifices that hold their pattern (published service life 2 years or more); solenoid valves that can be changed without disturbing pipework; and a spare-parts kit shipped with the system so the first failure does not stop the plant.

Monitoring and records

Where dust monitoring applies on site, the useful configuration is a system triggered by the monitor rather than by a clock: suppression runs when dust is detected, and the control log shows when it ran. Our published performance figure is PM10 reduction of 70% or more for correctly designed source control. Confirm the applicable limits and reporting requirements with your environmental team — we supply equipment and layout drawings, not compliance certification.
