This project aims to develop a comprehensive understanding of granular mixing mechanics in bladed mixers. The study will be carried out by means of newly developed advanced numerical and experimental techniques to generate particle scale information. The flow and mixing behaviour of particles under different conditions will be analysed at both micro- and macro-scopic levels. The research outcomes such as predictive equations will be tested by simulating and analysing complicated industrial mixing processes; modelling to improve granulation and breakage will be targets. It will significantly improve the design, optimisation and control of mixing processes that are widely used in many industries.Read moreRead less
Particle scale studies of powder mixing in bladed mixers. Powder handling and processing are widely used in both conventional and modern industries but rarely reach more than 60% of design capacity because of poor fundamental understanding. Such operations are important to Australia in view of the heavy dependence on raw materials processing (about 40% of the GNP). This project will tackle the core problems in powder mixing which is a key operation in many industries. Application of the research ....Particle scale studies of powder mixing in bladed mixers.
