The centrifugal sorting device 6 is installed on the upper interior of the housing 1 and is fixedly connected to the DC motor 3 on its left side. The power control box 7 is fixedly connected to the lower left side of the housing 1. The four support legs 8 are equidistantly fixedly connected to the bottom of the housing 1.

The power control box 7 is electrically connected to the DC motor 3 and the vibrating screen 10.
[0015] The centrifugal sorting device 6 includes a rotating shaft 11, a guide fan blade 12, a drum fixing block 13, a drum 14, and a rotating shaft limiting plate 15. The rotating shaft 11 is fixedly connected to the right side of the DC motor 3. The guide fan blade 12 is fixedly connected to the outside left side of the rotating shaft 11. The drum 14 is fixedly connected to the right side of the rotating shaft 11 through the drum fixing block 13. The rotating shaft limiting plate 15 is fixedly connected to the inside of the outer casing 1. The front end of the right side of the rotating shaft 11 is shaft-connected to the inside of the rotating shaft limiting plate 15.
[0016] The vibrating screening device 10 includes a screen support 16, a central clamping plate 17, a primary screen 18, a secondary screen 19, an end screen 20, a baffle plate 21, a discharge partition plate 22, a compression spring support 23, and a vibrating motor 24. Two central clamping plates 17 are fixedly connected inside the screen support 16. The primary screen 18, secondary screen 19, and end screen 20 are sequentially fixedly connected between the screen support 16 and the central clamping plate 17 from left to right.

[0017] The working principle of this invention is as follows: In use, the centrifugal drum and vibrating screen are first driven until the speed stabilizes. Graphite enters the rotating drum through the left feed inlet. Centrifugal force throws small particles out of the screen, while larger particles are pushed to the right to the coarse material outlet. The small particles after centrifugal separation fall into the vibrating screen and are further classified through three sections of screen plates. The discharge port baffle adjusts the vibrating screen frequency according to the flow rate to ensure separation stability. Coarse particles (right end of the drum), medium-sized qualified particles (left side of the vibrating screen), small particles (middle section of the vibrating screen), and fine powder (left end of the vibrating screen) are output separately.
