[0002] As the third-generation rare earth permanent magnet material, neodymium iron boron has a high magnetic energy product and is widely used in many fields. However, a large amount of waste is generated during the production and use of neodymium iron boron. If these wastes are not reasonably recycled, it will not only cause waste of resources, but also may have an impact on the environment. In the process of neodymium iron boron waste recycling, cleaning and screening are key links; Through retrieval, it is found that there is a cleaning and screening device for neodymium iron boron waste recycling with the application number CN118594905A. This prior art can push and convey the waste through a conveyor belt and a panel. During the conveying process, small-volume waste and impurities in the waste can be removed, and the surface of the waste can be cleaned by jetting air, without using clear water to avoid wasting water resources; In the prior art, cleaning and screening cannot be carried out simultaneously. Moreover, during the waste recycling process, some oily substances will be adsorbed on the surface of the waste, which cannot be cleaned by wind power. In addition, the prior art cannot effectively distinguish magnetic materials and non-magnetic materials through the device, and separate screening and cleaning, which requires additional manual and mechanical operations.
