The hierarchical device in the airflow crusher is a component used to control the particle size distribution of the air flow crushing product, which becomes fine powder through the grading device. In the future, particles that meet the fineness requirements are isolated by classifiers and returned to the grinding cavity for crushing. The graded device not only makes the granular size of the finished powder compact and the particle size is compact, but also reduces the particle grinding of the particles, which is of great significance to improve the smash efficiency.
Types (horizontal and vertical), blade structure and flow fields of the hierarchical wheels will affect the grading effect. Generally, only through the case, only passed only through The hierarchical wheel speed to control the granular particle size and hierarchical rotation speed, so that the product can reach a certain fine particle size. During the operation, the grading technology of the airflow crusher plays a vital and irreplaceable role. It can make the raw materials be separated from various different granular sections after being super refined, so as to meet customer needs Grane size segment raw materials. The hierarchical raw material of the air flow crusher is the basis of preparing the product structure to a certain extent. At the same time, he is also a material with a special function. Study and develop new and powerful decentralized devices. At present, there are already physical and chemical methods that can be applied. What is commonly used in chemical methods is to add decentralized additives to the material before the classification process, but this method increases production costs, and the dispersant may pollute the material, so it is only used under special circumstances. The hierarchical technology of the air flow crushing machine clarifies the influencing factors of the hierarchical flow field, designs a reasonable structural form, reduces the generation of local vortex, and makes the flowing state of the hierarchy as even as uniform. The design of the hierarchical field and the exploration of the new grading principle. By studying the differences in particle surface characteristics, interface status, and the behavior differences in different media and different force fields, find new principles, methods and channels, design a stable and adjustable force field, and target what appears in the process of ultra -fine grading process. Corresponding measures for other issues. For example, for the danger of explosion in ultra -microfin, carry out inert gas as a research of grading medium; tensile tests for ultra -emblem powder. Development and research has good decentralized performance and standardized operations that can implement standardized operations.
