Dust Suppression Systems
There are two distinct philosophies to control dust with water sprayers during materials handling process.
Low pressure (< 10 bar) and high water volume systems can be employed. This treatment philosophy is referred to as dust prevention. The spray system will discharge water directly on the material at the beginning of the transfer point. Being low pressure, the flow of water and droplets sizes are much bigger and hence referred to as wetting systems.
On the other hand, dust suppression systems (also known as misting systems) employ high pressure (> 50 bar) and low volume of water in the form of a fine atomised mist to capture dust that is already airborne and bring it back to the source.
Dust suppression and dust prevention systems are not exclusive; many operations have both systems configured to effectively control dust.
Dust-A-Side are leaders in dust suppression systems
With over 220 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.
Most 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’s systems are fully enclosed, air conditioned and come complete with dust-proof components.
To reduce the use of water and enhancing the system’s performance, binder products such as AquaTarp and HydroTac, including surfactants like HydroPlus can be incorporated.
HydroPlus helps to break the surface tension of water molecules to anything less than 10 microns to effectively collide and capture suspended particulate dust bringing it back to the source.
The addition of this additive is particularly effective when managing hydrophobic materials such as coal dust and other fine and ultra-fine dust.
Benefits of using a Dust-A-Side dust suppression system
- Reduces respirable dust by 80%+. Respirable dust (10 microns and less). This dust particulate matter can have major health impact.
- Reduces visual dust
- Minimises water usage
- Minimises conveyor slippage
- Eliminates excessive moisture content in the material / ore
- Reduces chute blockages
- Improves housekeeping standards
- Increases safe work areas during operation
Dust suppression system applications:
- Rail Wagons
- Transfer Points
- Tipping Areas
- Loading Terminals
- Storage Facilities
- Demolition Sites
- Quarries, and
- Rock Crushing Plants.
