DUST COLLECTOR IMPROVES VISIBILITY
QUEENSLAND ALUMINA LIMITED

GLADSTONE, QUEENSLAND
BACKGROUND
Queensland Alumina Limited (QAL) faced a major health and safety issue at their facility when they were loading and unloading raw products, using front-end loaders and tipper trucks into an A-Frame shed.
The process was creating a significant amount of airborne dust, which was hampering the visibility and creating a hazardous situation for heavy vehicle operators. The situation demanded an urgent solution to ensure the safety of the workers.
PROJECT OBJECTIVES
Queensland Alumina Limited had 3 objectives:
Improve visibility on worksite and for drivers
Reduce the amount of dust
Maintain project bottom line
As the primary concern was safety, and cost was not a limiting factor, BlastOne recommended a large-scale dust collector capable of removing a maximum amount of airborne dust to reduce the risk of accidents and enhance visibility in the shed.
The rental of a dust collector would allow better visibility within the shed for loading and unloading of material.
RESULTS
The installation of a large 60000cfm dust collector inside a 50ft container proved to be an effective solution. The dust collector enabled three air-changes per-hour within the A-Frame structure, significantly reducing the amount of airborne dust.
It not only improved visibility in the shed, but it also mitigated the risk of accidents and improved the overall air quality of the facility.
CONCLUSION
The implementation of a dust collector at the Queensland Alumina Limited facility proved to be a wise investment in terms of safety, productivity, and profitability.
The successful installation of the dust collector highlights the importance of investing in safety measures, which not only helps in maintaining the bottom line but also increases profitability in the long run.

Experience the BENEFITS
VISIBILITY
Dust collection units are an important component for blasting site environmental and personnel safety. The removal of dust and other hazardous air particles protects the employees on site, while also preventing harmful contaminates from escaping into the atmosphere without relying on personal respiratory equipment alone.
HEALTH
A dust collector is used to provide ventilation inside containment structures to maintain operator visibility and maintain the encapsulated area under a negative pressure. It is also important to dilute the levels of hazardous substances within the contained area to levels below the minimum requred protection factor for personnel within, as well as respirator equipment limitations.
ENVIRONMENTAL
Many older coatings contain a high percentage of lead which when pulverized into powder by abrasive blasting can form a hazardous and toxic dust. Company legal obligations on project sites are now requiring that a full dust-tight containment structure encapsulates all blasting operations to minimize the danger to personnel and the environment.

FREQUENTLY ASKED QUESTIONS
How do dust collectors work?
Dust laden air travels down the ductwork and enters into the dirty air inlet plenum at the rear of the dust collector. Here the heavier particles drop out of the air stream. The air is then drawn through a large bank of high efficiency filter cartridges where the dust is deposited on the outside of the filter cartridges. Filtered air passes through to the clean air plenum and passes through the fan blower to the atmosphere. The cake of dust on the cartridges is dislodged continuously by an automatic reverse pulse jet.Dust drops into the hopper of the collector and is transferred by a screw conveyor to a conveniently located dust outlet for easy transfer to a receptacle for disposal.
Do dust collectors run on diesel or electric?
Some job sites are different to others. Contractors know that they can save a lot of money when the job site has power available. That is why BlastOne offers a bi-powered dust collector. Run it on plant power, generator power, or use the inbuilt diesel engine — it’s your job, your choice.What's more cost effective? Skid or trailer mounted?
The most cost effective option for a mobile dust collector is to mount it on a skid base. The dust collector can either be moved around using a large yard forklift or craned on and off a truck. This option is good for projects which have long durations and the unit isn’t required to move around onsite much at all. The skid has fork pockets, rigging mounts and extendable/collapsible legs to make transportation easy.What are options for mobility?
Yard Towable TrailerThe next step up in mobility — if you have a long project duration (2+ months), the yard towable trailer gives the ultimate site portability. While it needs to be loaded on a trailer to be delivered to the site, once onsite, it can be moved easily, as required. The ultra-heavy duty wheels & axels will last you many years of hard service.
Highway Towable Trailer
The ultimate mobility. Perfect for projects that are short in duration (under 2 months). The highway towable trailer means that the dust collection system and power/fan unit are all mounted on a highway certified trailer meaning that the unit can be moved anywhere at any time.
