Abstract Particle scale modelling of comminution processes can provide significant insight into the flow of particles, their breakage, the effect of slurry, wear and energy utilisation within these machines. The ability to use such models to assist in faster and lower cost design of new comminution devices and in the improvement of existing ones will be critical to the ability of industry to respond to the substantive challenges facing mineral processing in the next decade. These challenges are reviewed and drivers for change are discussed. Understanding individual unit process performance needs to be in the context of the flowsheets in which they are used so this is also reviewed. Advances in particle based comminution modelling are presented with this work divided into two parts. This first part focuses on recent advances in particle based modelling of crushing. Three crusher types are used to demonstrate these capabilities: 1. Twin roll crusher 2. Cone crusher 3. Vertical Shaft Impactor (VSI) These show the nature and level of fidelity that is now possible to include in particle scale crusher models including breakage of non-spherical particles and prediction of the product size distribution and throughput.

高级粉碎建模：第 1 部分 – 破碎机

摘要 粉碎过程的粒子尺度建模可以提供对粒子流动、它们的破碎、泥浆的影响、磨损和这些机器内的能量利用的重要洞察。使用此类模型来帮助更快、更低成本地设计新的粉碎设备以及改进现有设备的能力对于工业应对未来十年矿物加工面临的实质性挑战的能力至关重要。审查了这些挑战并讨论了变革的驱动因素。了解单个单元过程性能需要在使用它们的流程图的背景下进行，因此也需要对其进行审查。这项工作分为两部分，介绍了基于粒子的粉碎建模的进展。第一部分重点介绍基于颗粒的破碎建模的最新进展。三种破碎机类型用于展示这些功能： 1. 双辊破碎机 2. 圆锥破碎机 3. 立轴冲击器 (VSI) 这些显示了现在可以包含在颗粒级破碎机模型中的性质和保真度水平，包括非-球形颗粒和产品尺寸分布和吞吐量的预测。
