At present, the market of China's crusher still has great potential, but there are not many really viable fist products. It still needs the invention and creation of scientific researchers and manufacturers to develop a crusher that can not only solve practical problems, but also has high efficiency, to fill the technical gap in China and even in the world.
Because crushers are widely used in all walks of life, great attention has been paid to the research and development of crushers at home and abroad. The AMC grinder developed by Japan's Ogawa Company is a typical vertical-axis graded micro-grinder. The vertical grinder system jointly designed and manufactured by Spanish Cravino Machinery Manufacturing Company and Egman Special Feed Company is also widely welcomed by European countries.
Modern engineering technology will require more and more high-purity and ultra-fine powders, and ultra-fine grinding technology will play an increasingly important role in the research and development of high-tech. High-tech industry is closely related to non-metallic minerals, and the development of high-tech and its industry should be considered in the future development of non-metallic deep processing technology and industry. Modern non-metallic deep processing technology and traditional industrial processing technology penetrate each other, and its development must consider the technological transformation and progress of traditional industries. In order to make better use of the limited non-metallic mineral resources, it is necessary to consider their comprehensive utilization.
The development and application of superfine crusher and Superfine Classifier are inseparable from the development of non-metallic mineral industry. Especially recently, the development of non-metallic mineral industry and the development of crusher industry in China have made the technology of superfine crushing and superfine classification further improved. Therefore, taking the development of non-metallic mineral industry as the background, this paper analyses the present situation and development market space of ultra-fine crusher and ultra-fine classifier in China.
The research of basic theory is very important for the development and application of ultra-fine grinding technology. Its ultimate goal is to guide practice and produce ultra-fine powder that meets the requirements. Its contents include particle size and surface physicochemistry of fine particles; description of grinding process; grinding characteristics and destruction process of ultrafine particles; study of optimal working parameters and grinding mechanism of ultrafine grinder; different grinding methods, such as impact, grinding, friction, shearing, crushing and denudation, are different. The energy consumption law, grinding efficiency, product fineness and energy utilization rate in grinding environment and their effects on the crystal structure and physicochemical properties of grinding materials, grinding environment, grinding aids and dispersants on product fineness, physicochemical properties and grinding efficiency, etc.
According to the different effects of different ultra-fine grinding methods on the crystal structure and physical and chemical properties of materials, combined with the use of materials, appropriate ultra-fine grinding technology and equipment are selected to avoid the adverse effects of ultra-fine grinding processing on the performance of materials, or to use ultra-fine grinding technology to selectively grind materials. Mechanical activation; purposefully improve the physical and chemical environment of ultrafine grinding by adding appropriate grinding aids, so as to improve grinding efficiency and reduce energy consumption.
