Australia is the world's biggest coal exporter, and black coal is Australia's largest export, worth around $A13.5 billion annually. Dense medium cyclones process the vast majority of tonnes fed to Australian coal preparation plants, and hence play a critical economic role in coal production. This project aims at providing substantial design and operational improvements through the application of a novel combined continuum and discrete modelling method. Specifically, the improvements targeted relate to better process and product control, a decrease in unit energy consumption and improvements in productivity, which, together with the research training offered, will further enhance Australia's leading position in global coal industry.

澳大利亚是世界上最大的煤炭出口国，黑煤是澳大利亚最大的出口产品，每年价值约135亿澳元。重介质旋流器处理了澳大利亚选煤厂的绝大多数进料吨，因此在煤炭生产中发挥了关键的经济作用。该项目旨在通过应用一种新的连续和离散建模方法，提供实质性的设计和操作改进。具体而言，目标改进涉及更好的过程和产品控制，单位能耗的降低和生产力的提高，这与提供的研究培训一起，将进一步提高澳大利亚在全球煤炭行业的领先地位。
