Dust Suppression for Coal Handling Plants
Engineered spray and fog systems for transfer towers, crusher houses, tipplers and stockpiles in coal handling plants.
Coal Dust Suppression System
Coal mining poses several explicit hazards, including breakdowns, flooding, and hazardous blasts. Dust created by coal handling plants and mining activities is a significant hazard as it can cause breathing-related issues for people, as well as maintenance issues for machinery. Additionally, dust can create a potentially hazardous environment. Every year, an unacceptable number of people are injured or killed in underground coal mining accidents or suffer from long-term health problems due to exposure to coal dust. High concentrations of coal dust in mines and processing plants can cause pneumoconiosis, explosions, injuries, and financial loss. Regulations limit respirable coal dust to 3 mg/m³. Coal dust is generated during drilling, blasting, loading, transport, storage, and processing, with moisture content varying by location.
Benefits of dust suppression: reduces respirable dust by 80%+, minimizes visual dust, limits water use, prevents chute blockages, improves housekeeping, and increases safe work areas.
Synergy Spray Systems provides comprehensive dust control solutions for coal mines and handling plants, including haul road suppression, dry fog systems for tipplers and conveyors, and transfer point dust suppression technologies.
What we need to design your dust control
Send these details and we can propose a system layout, nozzle count and water/power requirement.
Dust source
Crusher, transfer point, hopper, tippler, stockpile or haul road; photos or a drawing help.
Material
Coal, ore, limestone, fly ash, aggregates; moisture limit the process can accept.
Throughput & geometry
TPH, belt width, chute or enclosure dimensions and drop height.
Utilities
Water source and quality, available pressure, power supply and compressed air (for dry fog).
Operating pattern
Hours per day, interlocks with conveyors or tippler, and seasonal conditions.
Objective
Workplace dust, visible plume, stockpile loss or compliance target you need to meet.

Dry Fog Systems
Micron-sized fog that agglomerates fine dust at enclosed transfer points with very little added moisture.
ExploreCoal Yard Sprinklers
Rain-gun sprinklers around coal stockpiles to control wind-blown dust and help manage surface temperature.
ExploreWet Fog Systems
High-pressure water fog for crushers, screens and conveyors where light wetting of the material is acceptable.
ExplorePlain Water Systems
Spray headers, pumps and controls that wet the material at the source: simple, robust and economical.

Fog Cannons
Fan-driven mist cannons that throw fine droplets over open areas such as stockyards, demolition sites and loading zones.
ExploreQuestions about coal handling plants
Will it work alongside dust collection systems?
Yes it can be used
Is compressed air required for this system?
Pressure of around 50 bar and above is required for effectiveness and longer coverage
Can it be used on conveyor belts?
Yes we can arrange smaller attachment in the dust exchange areas of conveyors
Can we use RO water?
Yes as RO water is purified, it can be used
How many nozzles will be used?
Based on the coverage area, the total number of nozzles will be allotted
Will the water consumption be excessive?
Water consumption will be very less, approximately 35-60 ml per nozzle
Which dust suppression system is right for my plant?
It depends on the dust source and how much moisture your material can accept. Dry fog suits enclosed transfer points with little added moisture; plain-water sprays suit open conveyors and stockpiles; fog cannons cover open areas. We recommend after reviewing the site details.
Does the water need to be treated?
Fine fog nozzles have small orifices, so filtration is always needed and softened water is often recommended. Plain-water spray systems tolerate coarser filtration.
Can the system run automatically with the conveyor?
Yes. Systems are normally interlocked with the conveyor, crusher or tippler so they spray only when material is moving.
