Description

Technical Field

[0001] The invention relates to the technical field of NdFeB powder processing, and in particular to a NdFeB powder processing device and method. Background Art

[0002] NdFeB powder is an alloy powder composed of neodymium (Nd), iron (Fe), boron (B) and other elements, with excellent magnetic properties. The content of neodymium is usually between 20% and 25%. NdFeB powder can be processed into magnets of various shapes and sizes through various molding and sintering processes to meet different application requirements. When processing NdFeB powder, the raw materials need to be ground. Grinding is a complex and delicate process, which is directly related to the magnetic properties and physical properties of the final product.

[0003] At present, when the raw materials are ground, they are first crushed and then ground. In order to improve the grinding effect, multi-stage grinding is used for grinding. However, during grinding, the NdFeB powder that has met the requirements after the previous stage of grinding cannot be separated, so that the NdFeB powder that meets the requirements will still enter the next stage for grinding, which easily causes the NdFeB powder that meets the requirements to be over-ground, reduce the qualification degree, and affect the grinding effect. Secondly, during grinding, the raw materials are directly poured into the grinding device for centralized grinding, and cannot be ground in batches. The grinding uniformity is poor, which affects the grinding effect. Therefore, we propose a NdFeB powder processing device and method. Summary of the invention
