超细粉碎研究现状及其在磷矿加工领域中的应用

超细粉碎技术是将原材料加工成微米甚至纳米级别的一种重要技术手段，其研究能够有效提高资源利用率。阐述了超细粉碎过程中，由于机械力的作用，导致晶粒尺寸减小，晶体发生错位和缺陷，进而产生晶格畸变等晶体结构变化，并简述添加助磨剂对超细粉碎的影响；叙述了超细粉碎技术引起磷矿的性质及结构的变化，以及对释磷能力的影响。介绍了常用超细粉碎设备，着重叙述其工作原理、适用范围及优缺点等。 

Research Status on Ultrafine Crushing and Its Application in Processing of Phosphate Rock

Ultrafine crushing technology is an important technical means to process raw materials into microns or even nanometers, and its research can effectively improve resource utilization. Due to mechanical force, grain size reduction, crystal dislocation, and defects were introduced, in the process of ultrafine crushing, which will result in lattice distortion and other structural changes. The effect of grinding agents on ultrafine crushing was also listed. Furthermore, the effect of ultrafine crushing on the crystalline structure of minerals and the phosphorus release capacity of phosphate ore were mainly discussed. Meanwhile, the typical ultrafine crushing equipment and its applicable scope and advantages and disadvantages are introduced.
