[0001] The utility model belongs to the technical field of NbFeB magnetic crushing and sorting, in particular to a NbFeB magnetic crushing and sorting device. Background Art

[0002] After recycling neodymium iron boron magnets, there are usually a lot of waste and discarded magnets. These waste and discarded magnets are large in size and are not convenient for subsequent processing and storage. Through crushing, these waste and discarded magnets can be broken into smaller particles or powders, which are convenient for subsequent processing and utilization, such as re-pressing, refining, etc. At the same time, the crushed waste and discarded magnets can also reduce storage space and storage costs.

[0003] At present, in the process of crushing RuFeB magnetic materials, the existing RuFeB magnetic material crushing and sorting equipment produces crushed RuFeB magnetic particles of different sizes. The larger RuFeB magnetic particles may cause the filter holes of the screening structure to be blocked, requiring staff to operate and clear them. It does not meet the actual needs well and the sorting efficiency is poor.

[0004] For this purpose, a Ru-Fe-B magnetic crushing and separation device is proposed. Utility Model Content

[0009] Furthermore, a sealing plate is provided on the front side of the sorting box, a handle is fixedly connected to the outer surface of the sealing plate, and a side of the sealing plate away from the handle is fixedly connected to the slide plate.

[0010] Furthermore, support plates are fixedly connected to both ends of the lower surface of the sorting box.

[0011] Furthermore, the internal volume cavity at the bottom end of the sorting box is connected to a discharge pipe, and a valve is provided on the outer surface of the lower end of the discharge pipe.
