Description

technical field [0001] The invention relates to the technology in the field of ball milling equipment, and in particular provides a multifunctional ball milling device for efficiently preparing nano powder or slurry and a preparation process thereof. Background technique [0002] The realization of nano-metal or non-metal powders and compounds is an important basis for the development of technology in the new era. Nano-sized metal or non-metal powders and compounds have special physical and chemical properties. Aerospace and other fields have broad application prospects. At present, there are many techniques for making powder or compound nanometer, and there are two typical ones: liquid-phase method and solid-phase method. The liquid-phase method is mainly prepared from bottom to top through chemical reactions, mainly including sol-gel method, hydrothermal method, co-precipitation method, etc. These methods have complicated process, difficult product purification, poor batc...

AI Technical Summary

Problems solved by technology

The liquid-phase method is mainly prepared from bottom to top through chemical reactions, mainly including sol-gel method, hydrothermal method, co-precipitation method, etc. These methods have complicated process, difficult product purification, poor batch stability, and Environmental pollution is serious, so it is difficult to apply on a large scale

Solid-phase methods mainly include vapor deposition, plasma reaction, high-energy ball milling, etc.; and high-energy ball milling is currently the most widely used method for preparing nano-powders in industry in the world. Good, large quantity and high efficiency, but there are also disadvantages such as long action time, large product particle size, uneven particle size, and poor repeatability
