Abstract：
 The method for modifying surface of micrometer-level granules by adopting nano granules is characterized by that the small quantity of nano granules can be uniformly dispersed on the surface of large quantity of micrometer granules so as to obtain the composite granules material whose micrometer granules are covered with nano granules. The micrometer granule material can be calcium carbonate, wollastonite and talcum, etc. and nano granule material can be calcium carbonate, dsilicon dioxide, titanium dioxide and white carbon black, etc. It can be extensively used in fileds of paper-making rubber, plastics and coating industries.
