[0002] Rare earth compounds are a class of substances with important strategic significance and wide application value. Rare earth compounds are composed of rare earth elements and other elements and have unique physical and chemical properties. In the industrial field, rare earth compounds are widely used in permanent magnetic materials, catalysts, optical glass, ceramics, etc. For example, rare earth permanent magnetic materials have extremely high magnetic energy product and coercive force, and play a key role in motors, wind power generation, electric vehicles and other fields. In the field of catalysts, rare earth compounds can improve the efficiency and selectivity of chemical reactions, reduce energy consumption and environmental pollution. Rare earth compounds are also indispensable in the field of high technology. For example, in laser technology, rare earth-doped crystals and glasses can be used as laser gain media to generate high-intensity laser beams. In the field of electronic information, rare earth compounds can be used to manufacture phosphors for color displays, electronic ceramics, etc.

A rotating column 76 is fixedly connected to the outer surface of the rotating disk 75. The rotating column 76 passes through one end of the feed box 73 and is fixedly connected to a second gear 77. The second gear 77 is meshed with the first gear 66. By setting the track ring 74, the rotating disk 75 can be limited so that the rotating disk 75 can produce stable rotation. By setting the rotating column 76 and the second gear 77, the second gear 77 can be rotated when the first gear 66 rotates, and then the rotating column 76 drives the rotating disk 75 to rotate.
