Ultra-fine grinding technology is a new smashing technology developed to meet the requirements of modern technology. It has been widely used in many fields such as chemical industry, food, and medicine. Although the type of stereotypes in China is already comparable to that of manufacturers in the world, the development of such equipment in China was late and the foundation was poor. After importing and digesting imported equipment, some of them were only low-level imitations and were not improved and improved.
Due to the widespread use of pulverizers in various industries, the research and development of pulverizers at home and abroad attach great importance. At present, China's crushing machine market has great potential, but there are not many real-life competitive products. It has yet to be invented and created by a large number of scientific researchers and manufacturers, and it has been developed to solve practical problems and achieve high efficiency. To fill the technical gap between China and the world.
With the increase of social needs, equipment is facing a great challenge in terms of performance, product quality, and service life. Therefore, each equipment manufacturer is increasing its own research and development efforts, and constantly improving the equipment in the ultra-fine grinding work. The smashing strength, particle size distribution, grain type crystal form adjustment control technology, in order to achieve more efficient production.
This requires all machinery manufacturers to make targeted improvements to the ultra-fine powder processing equipment, and strive to achieve low energy consumption, high output, and no pollution in the ultra-fine grinding technology in China. Good performance, good dispersion and other unique performance advantages, improve China's ultra-fine grinding equipment competitiveness and share. Therefore, the development of ultrafine grinding technology should focus on the following aspects.
(1) Develop fine grading equipment and other ancillary equipment that are compatible with ultrafine grinding equipment. The closed circuit technology combined with ultra-fine grinding and grading equipment can increase production efficiency, reduce energy consumption, and ensure the quality of qualified products. It can be said that large-capacity, high-precision grading equipment is the key to the development of ultrafine grinding technology. It is necessary to conduct more research and development from the perspective of the entire process system, and to improve, complete, and improve other auxiliary process equipment such as grading equipment and product transportation equipment on the basis of existing comminution equipment.
(2) Improve efficiency, reduce energy consumption, and continuously improve and improve ultrafine grinding equipment. The key to ultra-fine crushing technology is the equipment. Therefore, it is first necessary to develop a new type of 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 ultra-fine grinding processes.
(3) Integration of equipment and process research and development. The ultra-fine crushing and grading equipment must be adapted to the specific material characteristics and product specifications, and the specifications and models are diversified. There is no super-fine crushing and grading equipment that is efficient and universal for any material.
(4) Develop multi-functional ultra-fine grinding and surface modification equipment. The combination of ultra-fine pulverization and drying processes, ultra-fine pulverization and surface modification, mechanical mechanochemical principle and ultra-fine pulverization technology can expand the application range of ultra-fine pulverization technology. With surface coating and solid miscibility, new materials with unique properties can be prepared.
(5) Development research and particle size detection and control technology related to ultra-fine grinding technology. Superfine grinding particle size detection and control technology is one of the important conditions for the continuous production of ultra-fine powder industrialization. Particle size testing instruments and measurement control technology are closely related to ultra-fine grinding technology and must be tackled by experts in these fields.
(6) The general development trend of non-metallic mineral raw materials or materials in the future is high purity, ultra-fine and functional. High-purity ultra-fine non-metallic mineral processing raw materials as a leader, the comprehensive development and utilization of various non-metallic minerals. Although high-purity ultrafine powders can be prepared by chemical synthesis, the cost is too high to be used for industrial production. The main method for obtaining ultrafine powders is still the mechanical smashing method. The difficulty in superfine comminution and grading technology relying on mechanical methods to obtain ultrafine powders is increasing, and the research depth is never-ending. Ultra-fine grinding technology is a comprehensive technology in many aspects, and its development also depends on the progress of related technologies, such as the processing of high-hardness and high-tensile wear-resistant components, high-speed bearings, and the measurement of submicron-sized particle size distribution.
The ultra-fine pulverization advances toward the nanometer level, and the dispersion and evaluation of the low-pollution, wear-resistant materials and nano-sized powders associated with this will become a huge technical obstacle, and research in this area will receive attention.
(7) Modern production not only pursues production efficiency and quality of finished products, but also develops in the direction of environmental protection and energy conservation. This is also true in the food and medicine industry. Looking at the requirements of modern social productivity, the overall development trend of China's ultra-fine material pulverization technology is toward the reverse development of low cost, high efficiency, high controllability, good dispersion, and stable quality.
