Description

Technical Field

[0001] The utility model relates to the technical field of samarium cobalt magnets, in particular to a grinding and pulverizing machine for producing samarium cobalt magnets. Background Art

[0002] Samarium cobalt is a permanent magnet material that exhibits good temperature characteristics in the rare earth permanent magnet series. Compared with neodymium iron boron, samarium cobalt is more suitable for working in high-temperature environments. At present, in order to improve the performance of samarium cobalt magnets and adapt to different application requirements, it is usually necessary to make samarium cobalt magnets into powder and undergo specific processing, so that samarium cobalt magnets can adapt to more different application scenarios.

[0003] An existing grinding and pulverizing machine for producing samarium-cobalt magnets (Announcement No.: CN217410926U) has at least the following disadvantages: although the grinding roller can be inspected and repaired through the feed port, it is inconvenient for workers to quickly deal with impurities adhering to the grinding roller during use. Failure to clean the roller in time will affect the grinding efficiency. In addition, the ground raw materials are directly fed into the mixing chamber for stirring, which easily leads to the contamination of insufficiently ground raw materials, thus hindering the subsequent processing of the raw materials.
