Effective transportation of bulk materials is crucial to the success of a wide range of industrial, mining and agricultural enterprises. From the point at which a mineral is mined or a crop harvested through to final refining, processing, and distributing to end users, there is need to transport bulk materials efficiently and safely from one place to another, whether over a few metres or thousands of kilometres.
Aurecon has been designing bulk materials handling systems for a range of industries for over 50 years. Since the late 1970s and early 1980s, major projects such as the Lucinda Bulk Sugar terminal and Dalrymple Bay Coal Terminal in Queensland, Australia, have grown our expertise in materials handling facilities. Since that time, Aurecon has developed an extensive track record in the successful design of bulk materials facilities for various mines, mineral processing facilities and especially bulk export terminals.
We are able to provide a fully integrated service across all engineering disciplines to deliver complete materials handling projects from feasibility to detail design to construction management and commissioning.
The design of bulk materials facilities requires specialist knowledge beyond that which is normally taught in the traditional disciplines of civil, structural, mechanical and electrical engineering. This specialist knowledge typically relates to the particular product being handled or the type of handling process involved. Some typical processes for which Aurecon offers specialist knowledge includes:
- Belt conveying
- Crushing and screening
- Dust control
- Feeding and dosing systems
- High-lift conveying
- Hot product conveying
- Liquids pumping
- Loading and unloading from road, rail, and ship transportation
- Pneumatic conveying and powder handling
- Product sampling
- Slurry pumping
- Stacking and reclaiming for open stockyards and sheds
- Storage in bins and silos
In a typical application, designs for machinery and structures are specifically tailored to suit the properties of the product being handled. Bulk density, lump size, flowability, hardness, temperature, dust emitting characteristics, sensitivity to environmental exposure, and corrosive or flammable properties are all carefully considered.
