The long term goal of this research activity is to contribute to the better understanding of the fundamentals driving comminution processes and apply this understanding to better design, optimise and control such processes as well as extend this understanding to related material breakage processes. In addition to size reduction of mineral bearing ore, it should be noted that comminution processes are central in the processing of a number of other materials such as pigment grinding in the paint industry, metal powder production in the automotive industry, metal hydride fabrication through mechanical alloying in grinding mills in the hydrogen hydride production sector as well as in "in-situ resource utilization" in space exploration activities. One ore breakage and wear mechanism that is common to all of these comminution processes is abrasion. Thus, the short term objective of this research is to develop a better understanding of ore breakage through abrasion and its relationship with abrasive wear and friction.

这项研究活动的长期目标是帮助更好地了解推动粉碎过程的基本原理，并将这种理解应用于更好地设计、优化和控制此类过程，并将这种理解扩展到相关的材料破碎过程。除了减少含矿物矿石的粒度外，还应当指出，粉碎过程在处理其他一些材料方面是核心的，例如油漆工业的颜料研磨、汽车工业的金属粉末生产、氢化物生产部门的研磨厂通过机械合金化制造金属氢化物以及空间探索活动中的“就地资源利用”。所有这些粉碎过程中共有的一种矿石破碎和磨损机制是磨损。因此，这项研究的短期目标是更好地了解通过磨损产生的矿石破碎及其与磨料磨损和摩擦的关系。
