The influence of grinding physical and chemical environment, grinding aids and dispersants on product fineness, physicochemical properties and grinding efficiency.For example, according to the different effects of different ultrafine vertical mill methods on the crystal structure and physicochemical properties of materials, combined with the use of materials, select the appropriate ultrafine vertical mill process and equipment to avoid the adverse impact of ultrafine vertical mill processing on the performance of materials, or use ultrafine vertical mill processing technology to selectively activate the powder materials; By adding grinding aids appropriately, the physical and chemical environment of ultrafine vertical mill can be improved to improve grinding efficiency and reduce energy consumption.Pay attention to the basic theory of ultrafine vertical mill. The research of basic theory is very important for the development and application of ultrafine vertical mill technology. Its ultimate goal is to guide practice and produce superfine powder that meets the requirements.
