中文摘要：

坡缕石是一种层链状含水镁质硅酸盐矿物，属世界稀缺的矿产资源。由于坡缕石的难磨属性，大大限制了其工业化开发应用进程。通过实验室试验，研究了干式细磨贵州大方纤维状坡缕石的磨矿工艺，表明在含有一定杂质的情况下，试验制定的磨矿工艺流程对纤维状坡缕石进行磨矿是可行的。

英文摘要：

Palygorskite is a kind of hydrous magnesium silicate mineral of layered chain structure and belongs to the rare mineral resources in the world. Its industrial development and application is greatly restricted by its hard grindabilty. In present work, a dry fine grinding process for fibrous palygorskite from Dafang, Guizhou is studied by laboratory test, and the results show that the experiment - established grinding technological process is feasible for fibrous palygorskite.
