[0024] The lifting cylinder 302 is welded in the roasting box 1 through a bracket, and the driving motor 301 is fixed to the middle of the top of the roasting box 1 by bolts. The driving motor 301 can drive the lifting and dispersing mechanism 3 to work, and the lifting cylinder 302 provides a lifting channel for the rare earth oxide.

[0025] The output shaft of the driving motor 301 is fixedly connected to the main gear 304, one end of the spiral shaft 303 is fixedly connected to the bottom end of the main gear 304, the spiral shaft 303 passes through the lifting cylinder 302, the driving motor 301 drives the main gear 304 to rotate, and the main gear 304 drives the spiral shaft 303 to rotate to lift the rare earth oxide.

[0026] The sub-gear 305 meshes with the main gear 304 , and one end of the stirring shaft 306 is fixedly connected to the sub-gear 305 . The main gear 304 drives the stirring shaft 306 to rotate through the sub-gear 305 , so that the stirring shaft 306 disperses the fallen rare earth oxides.

[0027] The heating plate 5 is embedded in the inner wall of the roasting box 1 , and the injection pipe 2 is formed on one side wall of the roasting box 1 . The rare earth oxide is injected into the roasting box 1 through the injection pipe 2 , and the heating plate 5 roasts and dries it.

[0028] The discharge hopper 4 is formed on the roasting box 1, and the baffle 8 is slidably arranged in the discharge hopper 4. The baffle 8 can seal the discharge hopper 4, and the rare earth oxides after roasting and drying are discharged and collected through the discharge hopper 4.
