摘　　要：目的:采用超微粉碎技术对蒙脱石散进行粉碎,以蒙脱石散的粒径为考察指标,同时检测蒙脱石中主要成分三氧化二铝含量。方法:在不能粉碎时间的基础上对蒙脱石散进行超微粉,检测其粒径的分布情况,并同时检测其三氧化二铝的含量是否符合标准。结果:蒙脱石散在粉碎时间为90S,粉碎温度为4℃时,粒径分布在范围内,三氧化二铝含量为18.11。结论:利用超微粉碎技术,将蒙脱石散进一步粉碎,其主要成分的含量没有发生变化,为其在吸附力的应用提供了一定的理论依据。Objective：using superfine grinding technology for grinding of montmorillonite powder,with montmorillonite powder particle size as examining index,while detecting montxnorillonite stone main component of Aluminum Oxide content. Methods：on the basis of can＇t crush time to superfine powder of montmoriUonite powder, testing its particle size distribution, and at the same time check whether its Aluminum Oxide content meets the standards. R.esults： montmorillonite powder in the grinding time for 90 S,when the grinding temperature of 4℃,particle size distribution in the range;Aluminum Oxide content is 18.11. Conclusion：the use of superfine grinding technology,montmoriUonite further crushing,its main composition content has not changed,for its application in adsorption force provides certain theoretical basis.
