Developing market
As the crusher is widely used in all walks of life, the research and development of the crusher are paid more and more attention both at home and abroad. ACM type mill developed Japan Hosokawa company, is a typical vertical grade Micro Mill, vertical mill system dimension machinery manufacturing company and the Spanish carat Eggers Man special feed company jointly designed and manufactured by European countries also greatly welcomed.
It is understood that there is great potential for China mill market, but the real vitality of the products is not much, and for the majority of researchers and manufacturers of inventions developed can not only solve the practical problems, and has high efficiency of the mill, to fill technology gaps and the world China.
development direction
The general trend of the future development of non-metallic mineral materials or materials is high purity, ultra-fine and functionalization. With high purity, superfine, non-metallic mineral processing materials as the leader, the comprehensive development and utilization of 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 so far. The main way to obtain ultrafine powder is still mechanical comminution, and the difficulty of superfine grinding and classification technology depends on increasing the depth of research. Superfine grinding technology is a combination of many aspects of technology, and its development depends on the progress of related technologies, such as the processing of high hardness and high toughness wear-resistant components, high-speed bearings and sub micron particle size distribution measurement. Therefore, the development of ultrafine grinding technology should focus on the following aspects.
(1) development of fine classification equipment and other necessary equipment matched with superfine grinding equipment. The closed circuit combined with superfine grinding and classification equipment can improve production efficiency, reduce energy consumption and ensure the quality of qualified products. It can be said that large quantity of treatment and high precision classification equipment are the key to the development of superfine grinding technology. More research and development should be carried out from the point of view of the whole process system. On the basis of the existing crushing equipment, we should improve, support and perfect other auxiliary process equipment, such as classification equipment, product delivery equipment, etc..
(2) improve efficiency, reduce energy consumption, and continuously improve and improve superfine grinding equipment. The key of superfine grinding technology is equipment, therefore, it is necessary to develop new super fine grinding equipment and its corresponding classification equipment, which seems more urgent. Grinding aids and surface active dispersants will be used in superfine grinding process.
(3) integration of equipment and process research and development. Ultrafine grinding and classification equipment must adapt to specific material characteristics and product specifications, specifications, models diversity, and there is no efficient and universal for all materials ultra-fine grinding and classification equipment.
(4) developing multi-functional superfine grinding and surface modification equipment. For example, the combination of superfine grinding and drying process, the combination of superfine grinding and surface modification, and the combination of mechanical and chemical principles with superfine grinding technology can expand the application scope of superfine grinding technology. Some new materials with unique properties can be prepared by means of surface coating and solid state mutual dissolution.
(5) development, research and particle size detection and control technology of superfine grinding technology. The particle size detection and control technology of ultrafine grinding is one of the important conditions to realize the continuous production of superfine powder. Particle size measuring instruments and measuring control technology are closely related to superfine grinding technology. They must work together with experts in these fields.
Superfine comminution is going into nanometer scale, and the dispersion and evaluation of low pollution resistant materials and nano powders will become a great technical barrier, and the research in this field will be paid more attention to.
Modern engineering technology will require more and more high purity superfine powder. Superfine grinding technology will play more and more important role in high and new technology research and development. High tech industries and non metallic minerals are closely linked in the future, non-metallic mineral processing technology development and industrial development must be considered in the development of high technology industry; modern non metal processing technology and processing technology of the traditional industry mutual penetration, its development must consider the technological transformation of traditional industries and in order to better progress; the application of non-metallic mineral resources are limited, we must consider the problem of comprehensive utilization.
