Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening device technology, and more specifically to a multi-layer screening device for ferrite magnetic powder processing. Background Technology
[0002] Ferrite magnetic powder, as an important magnetic material, has properties that are affected by particle size. Therefore, screening technology plays a crucial role in the production of ferrite magnetic powder. During the processing of ferrite magnetic powder, effective screening can remove unqualified particles, ensuring the performance and consistency of the final product. At the same time, the design of the screening device directly affects the efficiency of the production line. An efficient screening system can reduce downtime, improve production efficiency, and reduce production costs.
[0003] Currently, most existing screening devices for ferrite magnetic powder use a single-layer screening method. However, since there is only one layer of screen or filter medium, the efficiency of the entire screening process is relatively low. This means that it takes longer to process the same amount of material, thus reducing production efficiency.
[0004] Furthermore, during the sieving process of ferrite magnetic powder, fine ferrite magnetic powder particles tend to adhere to the inner wall. This phenomenon not only reduces the effective amount of material passing through each time, but more importantly, it causes uneven density distribution among different parts of the final screened product. This difference in density may affect the quality of subsequent processes and the performance of the final product.
[0005] To address the aforementioned problems, this application provides a multi-layer screening device for ferrite magnetic powder processing. Utility Model Content
