The hierarchical device of the airflow pulverizer is the key to control particle size
Airflow milling is large, high automation, fine product particle size, narrow particle size distribution, high purity, high activity, good dispersibility, etc., is widely used.
The hierarchical device in the airflow pulverizer is a component for controlling the particle size distribution of the gas stream, and turns into a fine powder by a grading device. The particles reached the fineness required in the future were isolated by the grading device, and returned to the grinding chamber. The grading device not only makes the particle size of the finished powder, the particle size distribution is compact, but also reduces the progression of the particles, which is important for improving the glue efficiency.
The type (horizontal and vertical), blade structure and flow field will affect the grading effect, in general, only control the grading granular grading wheel by grading wheel speed There is an advantageous value in the speed, so that the product reaches a certain fine particle size.
During the operation, the grading technology of airflow pulverizer plays a crucial, unsubstituted, it can make the raw material to make various different granularities to be effectively separated after passing through super refinement, resulting in Meet the particle size of the customer needs.
Airflow Crusher grading materials are based on the basis of the preparation of product structure, and he is also a material having a special function. Study and develop a new powerful dispersion device. At present, there is already possible to apply physical methods and chemical methods. The chemical method is commonly used to add a dispersion auxiliary agent before the pre-primary pulverization process, but this method will increase production costs, and the dispersant may contaminate the material, so it is only used in special circumstances.
Airflow Crusher Hierarchical Technology to clarify the influencing factors of the grading flow field, design reasonable structural forms, reduce the production of local eddy currents, so that the flow state of the grading flow field is as uniform as possible. Design and new grading principles of grading force field. Through the study of particle surface characteristics, interface state, and particles in different media and different force fields, find new principles, methods and pathways, design stable, adjustable power fields, arising from the ultrafine grade Research on other problems corresponding measures. For the danger of the explosion of ultrafine powder, an inert gas is carried out as a grading medium; a scratch test for supervoluents. Development and research have good decentralized performance, and test devices that can be standardized. ALPA provides customersAfter installing guidance services, after entering the field, the service engineer will go to the on-site guidance installation and provide system training for customer operators. During the practice of technicians, the training lecturers will continue to follow up the operational project to ensure that the project is organized, and the production line is stable and efficient.
