The development direction of non-metallic ultra-fine crushing technology Modern engineering technology will require more and more high-purity ultra-fine powder. Ultra-fine crushing technology will play an increasingly important role in the research and development of high-tech. The high-tech industry and non-metallic minerals are closely linked. In the future development of non-metallic mineral deep processing technology and industrial development, the development of high-tech and its industries must be considered; modern non-metallic deep processing technology and traditional industrial processing technology interpenetrate, and their development must be Consider the technological transformation and progress of traditional industries; in order to make better use of limited non-metallic mineral resources, its comprehensive utilization must be considered.

At the same time, in its development, utilization and deep processing, human survival and sustainable development must also be considered, and attention must be paid to environmental protection. The general development trend of non-metallic mineral raw materials or materials in the future is high purity, ultrafine and functional. Taking high-purity and ultra-fine non-metallic minerals as raw materials for further processing, we comprehensively develop and utilize various non-metallic minerals. Although high-purity ultrafine powder can be prepared by chemical synthesis, the cost is too high and it has not been used in industrial production so far. The main means of obtaining ultrafine powders is still mechanical crushing. The difficulty of ultrafine crushing and grading techniques relying on mechanical methods to produce ultrafine powders is increasing, and the depth of research is endless. Ultrafine crushing technology is a combination 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, and the measurement of submicron particle size distribution.

Therefore, the development of ultrafine crushing technology should focus on the following aspects.

(1) Develop fine grading equipment and other supporting equipment matching with ultra-fine crushing equipment. Closed-circuit technology combining ultra-fine crushing and classification equipment can improve production efficiency, reduce energy consumption, and ensure qualified product size. It can be said that large processing capacity and high-precision classification equipment are the key to the development of ultra-fine crushing technology. It is necessary to conduct research and development from the perspective of the entire process system, and to improve, complete and improve the classification equipment, product transportation equipment and other auxiliary process equipment on the basis of the existing crushing equipment;

(2) Improve efficiency, reduce energy consumption, and continuously improve and improve ultra-fine crushing equipment. The key to the ultra-fine crushing technology is equipment. Therefore, first of all, it is necessary to develop new ultra-fine crushing equipment and its corresponding classification equipment. The latter seems to be more urgent. Grinding aids and surface active dispersants will be used in the ultra-fine grinding process;

(3) Integration of equipment and process research and development. The ultra-fine crushing and classification equipment must adapt to the specific material characteristics and product indicators, and the specifications and models are diversified. There is no ultra-fine crushing and classification equipment that is efficient and versatile for any material;

(4) Develop multifunctional ultra-fine crushing and surface modification equipment. Such as the combination of ultrafine crushing and drying processes, the combination of ultrafine crushing and surface modification, the combination of mechanochemical principles and ultrafine crushing technology, can expand the application range of ultrafine crushing technology. With the help of surface coating and solid-state mutual dissolution, some new materials with unique properties can be prepared;

(5) Development and research of particle size detection and control technology related to ultrafine crushing technology. The particle size detection and control technology of ultra-fine crushing is one of the important conditions for industrialized continuous production of ultra-fine powder. The particle size testing equipment and the control technology of the determination are closely related to the ultra-fine crushing technology, and we must work together with experts in these fields.
