Analysis and optimization of flow behavior and impacting performance of the Nd-Fe-B particles in fluidized bed air jet milling using 3-D FDEM

Fluidized bed air jet milling is a key process for preparing high-performance Nd-Fe-B rare-earth (RE) permanent magnet particles, but its process parameter system and equipment structure are still in constant trial and error, which makes the magnetic particles size distribution and production effici...
