Abstract

Efficient mixing of binary particle systems is essential in process engineering, as it directly impacts product quality, stability, and cost. Traditional evaluation methods rely on empirical modeling from the theoretical assumptions or macroscale characterizations, both remaining time- and cost-intensive. In this study, X-ray computed tomography (XCT) is employed to perform non-destructive three-dimensional imaging of particulate systems. This advanced technique enables detailed characterization of microstructural features and spatial arrangements, yielding critical insights into mixing conditions at the microscale, and is quantified by tailored evaluation metrics. Machine learning-enhanced image segmentation enables efficient particle identification in 2D cross-sections from 3D XCT data. This framework enhances XCT-based feature extraction, enabling simultaneous qualitative observation and quantitative analysis to optimize and improve chemical engineering processes and product quality.

通过机器学习辅助空间分布分析，揭示非破坏性3D XCT成像中的粒子混合

二元粒子系统的有效混合在工艺工程中是必不可少的，因为它直接影响产品的质量、稳定性和成本。传统的评估方法依赖于理论假设或宏观尺度特征的经验建模，既费时又费钱。在本研究中，采用x射线计算机断层扫描（XCT）对颗粒系统进行非破坏性三维成像。这种先进的技术能够详细表征微观结构特征和空间排列，对微观尺度的混合条件产生关键的见解，并通过定制的评估指标进行量化。机器学习增强的图像分割能够从3D XCT数据中有效识别2D横截面中的颗粒。该框架增强了基于xct的特征提取，能够同时进行定性观察和定量分析，以优化和改进化工工艺和产品质量。

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
