介绍了搅拌磨超细粉碎的工艺过程和助磨剂对超细粉碎效果的影响，探讨了搅拌磨超细粉碎的行为特征。研究表明，用搅拌磨可制得平均粒径小于１μｍ的超细滑石粉，工艺简单，效率高，产品无污染；助磨剂主要是通过与滑石粉的吸附作用，降低矿浆粘度，提高磨矿过程的分散性而产生助磨作用；试验证实间歇式搅拌磨的超细粉碎过程符合Ｃｈａｒｌｅｓ定律，并建立了搅拌磨超细粉碎的模型 The effect of grinding process and grinding aids on the effect of ultrafine grinding was introduced. The behavior characteristics of the grinding process were discussed. The research shows that the ultrafine talcum powder with the average particle size less than 1μm can be obtained by the agitating mill. The process is simple, the efficiency is high, and the product is non-polluting. The grinding aid mainly reduces the viscosity of the ore slurry and improves the grinding The dispersion of the process to produce a grinding effect; experiments confirmed intermittent grinding mill ultrafine grinding process consistent with Charles’s law, and the establishment of a stirred mill ultra-fine grinding model
