Dust Suppression Systems

There are two ways to control fugitive dust with water sprays during any materials handling process.

You can ‘nip it in the bud’ with a low pressure (< 10 bar) dust prevention system that uses large volumes of water at close range to contain the errant dust, usually close to the source such as the beginning of the transfer point. Being low pressure, the droplets are much coarser, so this is more accurately described as a wetting system rather than a misting system.

And/or you can utilise a dust suppression misting system which conversely uses lower volumes of water at high pressure (> 50 bar) to add a fine atomised mist to the air and thus capture and subdue dust particles that are already airborne.


Dust suppression and dust prevention systems are not exclusive; many operations have both systems configured to effectively control dust.

No one knows more about dust suppression systems.

With over 100 fully customised and purpose-built dust suppression systems in use globally, from conveyors to transfer stations, Dust-A-Side is an acknowledged leader in this field.

All of these systems are triggered by remote control sensors and programmable logic controllers with fully automated, self-cleaning water filtration systems.

The pump modules are constructed from industrial grade components and are UL and CE rated for utmost performance and reliability.

Due to the harsh operating environment of heavy industry, Dust-A-Side Australia’s systems are fully enclosed, air conditioned and come complete with dust-proof components.

To reduce the use of water and enhance the system’s performance, binder products such as Aquatarp and Hydrotac, and surfactants like Hydrowet can be incorporated.

Hydrowet helps to break the surface tension of water particles, leading to smaller water droplets (between 5 and 10 microns) that attract dust particles to them, via agglomeration.

This process is particularly effective when managing hydrophobic materials such as coal and other fine ores.

Benefits of a misting system to suppress dust.

  • Reduces respirable dust by 80%+. Respirable dust (typically less than 10 microns), is the dust that can cause everything from irritation and vision impairment to major health risks.
  • Reduces visual dust
  • Minimises water usage
  • Minimises conveyor slippage
  • Eliminates excessive moisture content in material
  • Reduces chute blockages
  • Improves housekeeping standards
  • Increases safe work areas during operation

Dust Suppression System Applications:

  • Stockpiles
  • Conveyors
  • Rail Wagons
  • Transfer Points
  • Tipping Areas
  • Loading Terminals
  • Storage Facilities
  • Demolition Sites
  • Excavations
  • Quarries, and
  • Rock Crushing Plants.
