The project aims to develop better mixing theories to support industrial applications. Effective mixing of granular materials such as aggregates in building industry and stockpiles in mineral processing is important for creating homogeneous products, yet industrial mixers lack scientific design and operate with no control of mixture quality. The project aims to establish a new general continuum mixing theory, which will be validated against X-ray measurements of grain motions within small mixers. By describing the theory using an accurate computational method, the simulations of these mixers will be scalable, and would help deliver predictions for particle mixing in much larger operations. Other expected outcomes are to control mixture quality and reduce industry reliance on costly and time-consuming trial-and-error experiments.

该项目旨在开发更好的混合理论以支持工业应用。建筑行业的骨料、选矿行业的矿料等颗粒物料的有效混合对于生产均质产品至关重要，而工业混合机缺乏科学的设计，运行时混合料质量无法控制。该项目旨在建立一个新的通用连续混合理论，这将是验证对X射线测量颗粒运动在小型混合器。通过使用精确的计算方法描述理论，这些混合器的模拟将是可扩展的，并将有助于在更大的操作中提供颗粒混合的预测。其他预期的结果是控制混合物质量，减少工业对昂贵和耗时的试错实验的依赖。
