The project aims to develop the means of fabricating single-crystal mullite fibres from topaz that are suitable for reinforcement of metal and ceramic matrix composites. Single-crystal mullite is the most sought after fibrous additive, but is not available commercially. It is expected to attract an immediate clientele in laboratories and companies servicing the aviation industry and the military. This will allow large deposit of topaz in Torrington, NSW to be used to develop a high-value niche product (fibres) and a large-volume, low-value product (fluoride). This will provide significant economic and environmental benefits and it addresses the research priorities - Resources and Advanced Manufacturing.Read moreRead less
Modelling and Characterisation of Stringy/Compressible Bulk Materials. The development of new technologies in the treatment of waste products, recycling of green and paper waste and the use of biomass fuels has created the need for a new approach in the handling of non-conventional bulk solids. The Mohr-Coulomb models that are traditionally used to characterise granular materials do not adequately describe the nature of these stringy and compressible bulk solids. This project will address this ....Modelling and Characterisation of Stringy/Compressible Bulk Materials. The development of new technologies in the treatment of waste products, recycling of green and paper waste and the use of biomass fuels has created the need for a new approach in the handling of non-conventional bulk solids. The Mohr-Coulomb models that are traditionally used to characterise granular materials do not adequately describe the nature of these stringy and compressible bulk solids. This project will address this problem by developing new constitutive models and characterisation techniques for this class of materials. This work will provide the necessary tools to address a series of pressing problems in several emerging technologies.Read moreRead less

It is important to improve the quality of their Talcom body powder, baby powder and other cosmetic products involving talc. The areas that can and need to be improved are shining characteristics, assessing the slip properties as well as developing the cosmetic chemistry of talc and other additives. The proposed project will generate: a) simple but reliable test methods for measuring slip and shine, b) methods for control of the physical and chemical characteristics of talc blends, c) mathematical model(s) for property and process control, which is useful to improvement of the final talc properties and in-use service.Read moreRead less

Quantification and Modelling of Particle Flow Mechanisms in Conveyor Transfers. A critical area of solids handling and processing is the transfer of bulk material between conveyor belts. Design of conveyor transfers rely heavily on trial and error and/or experience and cannot cope with the complexities of varying particle properties and process requirements. Poor transfer designs can result in reduced QC and service life, significant maintenance/environmental costs and safety concerns. The main ....Quantification and Modelling of Particle Flow Mechanisms in Conveyor Transfers. A critical area of solids handling and processing is the transfer of bulk material between conveyor belts. Design of conveyor transfers rely heavily on trial and error and/or experience and cannot cope with the complexities of varying particle properties and process requirements. Poor transfer designs can result in reduced QC and service life, significant maintenance/environmental costs and safety concerns. The main aims of this project are experimental and theoretical investigations into the flow of particulates through conveyor transfers. This will result in: development of a novel conveyor transfer facility; quantification of transfer parameters and data; development of models to simulate and assist in the design of complete transfers.Read moreRead less

The purpose of this project is to investigate the recovery of valuable particles, referred to as cenospheres, from the fly ash waste of coal fired power stations. An understanding of the complex gravitational settling behaviour of fly ash suspensions in inclined channels will lead to a new technology for recovering and concentrating the particles.
Particle scale modelling of dense medium cyclones in coal preparation. Australia is the world's biggest coal exporter, and black coal is Australia's largest export, worth around $A13.5 billion annually.

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.Read moreRead less
