Abstract Grinding typically is the most cost-intensive stage of mineral beneficiation plants. Besides other design and operational parameters, grinding media have a crucial effect on the energy consumption of tumbling mills and generally on their operating costs. Steel balls are the most typical grinding media. However, in recent years, various media shapes with different properties have gained interest in the market, and their efficiencies were compared with balls. This study presents a comprehensive review of the impact of various media geometries on grinding factors (load behavior, power draw, toe, shoulder, contact mechanism, kinetic energy) and the product particle size in tumbling mills.

介质形状对滚筒磨机性能影响的研究——综述

摘要 研磨通常是选矿厂成本最高的阶段。除了其他设计和操作参数外，研磨介质对滚筒磨机的能耗及其运营成本也有至关重要的影响。钢球是最典型的研磨介质。然而，近年来，市场上对各种具有不同特性的介质形状产生了兴趣，并将它们的效率与球进行了比较。本研究全面回顾了各种介质几何形状对研磨因素（负载行为、功率牵引、趾部、肩部、接触机制、动能）和滚筒磨机产品粒度的影响。
