从矿物晶体的内聚力出发，讨论了在机械力作用下，矿物颗粒的碎裂细化过程和功耗，以及伴随粉体颗粒的细化，矿物的晶体结构和其它物理化学性质的变化。超细加工是机械力克服矿物晶体的内聚力，并对其作功导致矿物颗粒破碎和细化的机械力化学过程；在这过程中，矿物的晶体结构和性质发生多种变化；利用这些变化，可优化矿物超细粉体和制品的性能；选择超细粉体的最佳加工粒度，一方面可节能降耗，另一方面可减少机械力对矿物晶体性质的破坏。
Based on the cohesion of mineral crystals, the process of fission fission and power consumption of mineral particles under the action of mechanical force, as well as the changes of the crystal structure and other physicochemical properties accompanying with the refinement of the powder particles are discussed. Microfabrication is a mechanical force that overcomes the cohesion of mineral crystals by mechanical forces and causes mechanical fracturing and refining of mineral particles. In this process, the crystal structure and properties of the minerals undergo a variety of changes. Using these changes , Can optimize the performance of ultra-fine mineral powder and products; choose the best processing particle size of ultra-fine powder, on the one hand can save energy and reduce consumption, on the other hand can reduce the mechanical force on the destruction of mineral crystal properties.
