The general development trend of non-metallic mineral raw materials or materials in the future is high purity, superfine and functionalization. Taking the high-purity and ultra-fine non-metallic mineral deep processing raw materials as the leader, comprehensively develop and utilize various non-metallic minerals. Although high-purity ultrafine powders can be prepared by chemical synthesis, the cost is too high to be used in industrial production.The main way to obtain ultra-fine powder is still mechanical comminution. The difficulty of ultra-fine comminution and classification technology is increasing, and its research depth is endless.Superfine comminution technology is the synthesis of many technologies, and its development also depends on the progress of related technologies, such as the processing of high hardness and high toughness wear-resistant components, high-speed bearings, submicron particle size distribution measurement and so on. Therefore, the development of ultrafine vertical mill technology should focus on the following aspects.
