Dust suppression at Australian grain terminals
With a bumper grain harvest In Australia grain traders and exporters have been looking for alternatives to get their product to market and preserve the welfare of terminal workers in the process.
With increased loading activities, there is more dust being generated and exporters are looking for innovative ways to reduce the impact of grain dust on employees and community.
“Blue Water Misting (BWM) has innovative solutions for dust suppression at grain terminals,” said James Davenport from BMG.
“One of the unique selling points of the company’s Dry Fog Dust Suppression Systems is that they add less than 0.25% moisture so they can work with grain.”
Dry fog systems
Mr Davenport said that because dry fog creates very fine particles that float in the air, when they collide with dust particles do they drop out of the air meaning that overall wetting of cargo is less than 0.5%.
He explained that the company specialises in dust suppression systems which are tailor made for each client after reviewing the site and looking at the sources of dust.
For one client in south Australia, BWM undertook a site survey where after identifying the sources of dust, dry fog systems were installed at a number of dust generation points.
This points included truck dump to hopper, container stuffing, ship loading spout and truck filling to the truck to feed vessel.
The installations reduced the dust at site by more than 90% resulting in far less community pressure and less material loss.
Another of BWM’s clients is a grain blending facility in rural Victoria.
The site has had issues with employee health and escape of dust from doors resulting in community complaints.
BWM fitted an extraction system to the building near the door creating a negative pressure in the shed. This prevented fugitive dust escaping out the door when opening.
A series of dry fog spray bars was also fitted to the shed that dropped the fugitive dust out of the air and reduced dust in the shed by 80%.
BWM has to date supplied Hatch based, Hopper mounted (inlet and outlet), ship loaders, buildings and yard locations as well as fog cannons.
