Mines and Quarries

Crushing, screening and moving rock throws up large volumes of dust. It damages lungs, wears out machinery, coats everything nearby and draws complaints from neighbours and regulators.

Where dust comes from

• Primary and secondary crushers
• Vibrating screens
• Conveyor transfer points and discharge chutes
• Loading and unloading of trucks and bins
• Grinding and bagging in processing plants

How we control it

Each source is enclosed as far as practical and connected to an extraction system sized for it. The dust-laden air is cleaned before discharge, and the collected material can often go back into the process instead of being wasted.

What we provide

• Pulse jet bag filters and dust collectors
• Cyclone separators for heavier particles
• Wet scrubbers where the dust is sticky or the process is damp
• Hoods, enclosures, ducting and fans built for abrasive dust
• Ventilation and cooling for motor control centres, control rooms and enclosed plant areas
• Maintenance support, because dust systems only work if filters and fans are looked after

We design for the reality of these sites: heavy dust loads, harsh conditions and equipment that has to be easy to service.
