Development direction of pulverizers

The overall development trend of non-metallic mineral raw materials or materials in the future is high purity, ultrafine, and functionalization. Taking high-purity and ultra-fine non-metallic mineral deep processing raw materials as the leader, we comprehensively develop and utilize various non-metallic minerals. Although high-purity ultrafine powders can be prepared through chemical synthesis, the cost is too high and has not been used for industrial production until now. The main method of obtaining ultrafine powder is still mechanical crushing, and the difficulty of using mechanical methods to produce ultrafine powder depends on the ultrafine crushing and grading technology, and its research depth is endless. Ultra fine comminution technology is a synthesis of various 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, sub micron particle size distribution measurement, etc. Therefore, the development of ultrafine crushing technology should focus on the following aspects.
(1) Develop fine classification equipment and other supporting equipment that are compatible with ultrafine crushing equipment. The closed circuit process combining ultrafine crushing and grading equipment can improve production efficiency, reduce energy consumption, and ensure the particle size of qualified products. It can be said that large processing capacity and high-precision classification equipment are the key to the development of ultrafine crushing technology. We need to conduct research and development from the perspective of the entire process system, and improve, support, and improve other auxiliary process equipment such as grading equipment and product conveying equipment on the basis of existing crushing equipment.
(2) Improve efficiency, reduce energy consumption, continuously improve and improve ultrafine crushing equipment. The key to ultra-fine crushing technology is equipment, therefore, the first step is to develop new ultra-fine crushing equipment and corresponding classification equipment, which seems more urgent. Grinding aids and surface active dispersants will be applied in the ultrafine grinding process.
(3) Integration of equipment and process research and development. The ultra-fine crushing and grading equipment must adapt to specific material characteristics and product indicators, with diverse specifications and models, and there is no high-efficiency and universal ultra-fine crushing and grading equipment for any material.
(4) Develop multifunctional ultrafine crushing and surface modification equipment. By combining processes such as ultra-fine grinding and drying, ultra-fine grinding and surface modification, and combining mechanochemical principles with ultra-fine grinding technology, the application range of ultra-fine grinding technology can be expanded. By utilizing surface coating and solid-state mutual solubility, new materials with unique properties can be prepared.
(5) Develop and research particle size detection and control technologies related to ultrafine crushing technology. The particle size detection and control technology of ultrafine grinding is one of the important conditions for achieving industrial continuous production of ultrafine powder. The control technology of particle size testing instruments and measurements is closely related to ultrafine crushing technology and must be jointly researched with experts in these fields.
Ultrafine grinding is advancing towards the nanoscale direction, and the dispersion and evaluation of low pollution wear-resistant materials and nanoscale powders related to this will become a huge technical obstacle. Research in this area will be valued.
Modern engineering technology will require more and more high-purity ultrafine powders, and ultrafine crushing technology will play an increasingly important role in high-tech research and development. The high-tech industry is closely related to non-metallic minerals, and the development of high-tech and its industries should be considered in the future development of non-metallic ore deep processing technology and industry development; Comparison between modern non-metallic deep processing technology and traditional industrial processing technology
