A feed hopper 4 is provided on the top of the inclined guide sleeve 3, the spiral plate 6 is welded to the inner periphery of the roller 2, and the heating tank 7 is installed on one side of the support frame 1.

[0027] When in use, the support frame 1, the roller 2, the spiral plate 6 and the heating tank 7 are used to provide a set of drying and screening integrated mechanisms for the recycled rare earth polishing powder, so that the recycled rare earth polishing powder can be screened while being dried, thereby improving the efficiency of rare earth recycling.

[0028] The present invention also includes that powder discharge ports 21 are equidistantly provided on the outer periphery of the discharge end of the roller 2, a metal filter screen 22 is welded to the powder discharge port 21, annular tracks 23 are welded to the outer periphery of both ends of the roller 2, and track wheels 24 for rolling support of the annular track 23 are respectively installed on both sides of the top of the support frame 1.

[0029] The present invention also includes that the spiral plate 6 is a hollow structure, an air inlet pipe 61 is connected to the center of one end of the spiral plate 6, the air inlet end of the air inlet pipe 61 is connected to a rotary joint 62, and the end of the spiral plate 6 away from the rotary joint 62 is connected to an exhaust pipe 63, and the air outlet end of the exhaust pipe 63 is arranged at the discharge end of the roller 2.

[0030] For heat treatment, illustratively, Figure 1-4 As shown, the utility model also includes a ceramic heating tube 71 installed in the heating tank 7, an air pump 8 installed on the top of the heating tank 7, the exhaust end of the air pump 8 is connected to the air inlet end of the heating tank 7, and the exhaust end of the heating tank 7 is connected to the rotary joint 62 through a metal tube 72, and the outside of the heating tank 7 and the metal tube 72 are both wrapped with thermal insulation cotton.

[0031] When in use, the air inside the heating tank 7 is heated by the ceramic heating tube 71, and the heated air is sent by the air pump 8 to the inner cavity of the spiral plate 6 with a hollow structure through the rotary joint 62, so that the spiral plate 6 is heated.

[0032] The utility model also includes that a shaft sleeve 25 is provided at the center of the feed end of the roller 2, and a motor 5 is installed at the end of the inclined guide sleeve 3 away from the roller 2.
