Modern engineering technology will need more and more high purity ultra-fine powder , fine grinding technology in high - tech research and development will play an increasingly important role . Purity ultrafine powder by chemical synthesis , but the cost is too high for industrial production has so far failed . The primary means of access to ultra-fine powder is stillmechanical grinding , increasing the difficulty of preparation of the ultrafine powders depends ultrafine grinding and classification technology machinery , the depth of their studies endless . Ultrafine grinding technology is the a multifaceted technology of comprehensive , its development depends on advances in related technologies , as hard and high-toughness wear-resistant components of processing, high - speed high-strength bearing manufacturing submicron particle size distribution measurement .
(1) the integration of research and development of equipment and technology . Ultra-fine grinding and classification equipment indicators, scale models must be adapted to the specific properties of materials and product diversification, rather than the existence of any material is efficient universal ultra-fine grinding and classification equipment ;
( 2) the development of multi-functional ultra-fine grinding and surface modification equipment . Combination such as the ultra-fine grinding and drying processes , the combination of ultra-fine grinding and surface modification , the principle of mechanical chemistry with ultrafine grinding technology combined , can expand the range of applications of ultrafine grinding technology . By means of a surface coating, solid miscible phenomenon , will be prepared by some of the new materials with unique properties . In the field of materials , special new materials prepared by mechanical alloying .
