These properties make CuO a potential candidate in a wide range of applications such as antibacterial activity [1, 2], catalysis activity [3], as antioxidant [1] and in electrochemical materials [2].
Today, one of the ultimate challenges faced in materials science and engineering research is to synthesize pure nanocrystalline materials with desired properties, structure and composition for certain applications [4].

Introduction With increasing broaden of research and application of nano materials, nano magnetism, nano ceramic, nano solid lubrication and nano catalyze materials are hopefully applied in large scale, among which, nano solid material is to be one of the most important material.
Preparation of nano materials and their specialities research grows up as one of the most active front in tribology field and gets high attention from material science, physics and chemicals[2].
Meanwhile, material of ball is also correlative with granule size and rigidity of raw material and so on, mohs rigidity of ball should be three times larger than raw material, and the general materials for milling ball are glass, alumina, zirconia, steel etc.
While, mixing speed can’t go up unlimitedly, since it has been limited by factors such as motor power, materials intensity of ball, muddler and mixing barrel.
