Abstract：The equipment of surface modification and complex of powder is an important device to accomplish the modification and complex process.The design thought of typical device for surface modification and complex of nano-sized and micron powders was supposed,which was based on the research of the structure characteristics of nowadays equipments and the operating principle of surface modification and complex of nano-sized and micron powder.In this designs,there were 2 groups(4 bigger and 4 smaller) spray nozzles under the half ellipsoid,and these nozzles was symmetry and opposite,each nozzle was α(α>90°)angle with the generatrices of the half ellipsoid so as to be beneficial to disperse and blend of powder and modifiers.
