An innovative dust suppressing truck body has been designed by Austin Engineering for improved dust control in off-highway dump trucks.
There is increasing focus on dust control at mine sites across Australia, given the health impact of dust generated by mines on local communities.
Recently, the New South Wales Environment Protection Authority (EPA) introduced the Dust Stop Program, which enforces new standards on dust control, aiming to achieve an 80 per cent dust reduction.
Loading, dumping and moving overburden is a major source of dust emissions at coal mines. The dumping process can generate about 25% of dust emissions in a typical coal mining operation.
A recent government report found that coal mines can and will need to improve their dust management practices by developing and implementing dust management plans for coal mining operations and properly maintaining dust control equipment to ensure suitable mitigation.
Some of the methods employed by mine sites to manage dust emissions include minimising road haul distances and traffic, use of enclosed conveyors and water sprays on stockpiles. However, there are no specific tactics currently employed to minimise dust emissions generated specifically by dump trucks.
The patent pending Westech flow control body by Austin Engineering has a revolutionary floor design that controls the flow of material out of the body during dumping, minimising dust emission.
Austin Engineering’s dust suppressing truck body is designed to keep the centre of gravity of the load forward of the rear axle longer while in the dump cycle, reducing material surge as the load leaves the truck body, thereby controlling the flow of material.
In a traditional dump truck body, the material exits by surging down the floor as the body rotates, with the major part being released during the last part of the dumping process, resulting in excessive dust generation.
However, controlled dumping by the Westech flow control body ensures that the major part of the dumping process happens in layers rather than in a solid mass surging out of the body. This more even flow greatly reduces dust generated during dumping.
In addition to improved dust control, the Westech flow control body’s controlled dumping results in lower friction on the steel floor causing less wear, reducing the need for liner kits and extending body life. The reduction in material surge as the load leaves the truck body also eliminates lift at the front of the truck, making the truck safer and more stable.
The Westech flow control body is available for all truck brands and models in combo (coal and overburden), coal or overburden designs.
The Westech flow control body for off-highway dump trucks is manufactured by leading non-OEM engineer and manufacturer Austin Engineering.
