Passive Control of Dust Emissions from Belt Conveyor Systems

点击翻译按钮获取中文摘要

Belt conveyor systems are employed extensively to transport bulk materials in a great many industries, particularly those associated with mining and mineral processing. Belt conveyor installations are becoming longer and belt speeds significantly faster, resulting in increased dust emissions. An estimated 16 billion litres of water per annum is used by the Australian Black Coal Industry alone on dust suppression. This project will develop passive dust control technology, requiring no external energy or suppressants. This will be achieved through the development of numerical methods verified by rigorous experimental work. This will lead to significant cost savings, improved employee health and safety and reduced environmental impact.
