The rotating frames 150 are close to each other through the power part, and the bag body can be discharged through the opening by the bag withdrawing auger 151. The magnetic powder falls into the separation bin 141 and is broken up by the breaking pieces 162.

Then the magnetic powder is conveyed into the boiling chamber 210 by the screw conveyor, at this time, the driving ring barrel 234 continuously rotates, the blocking ball 231 continuously moves in the control ring 223, when the booster fan 226 supplies air, if the blocking ball 231 blocks one of the air supply ports, the air outlet of one unidirectional boiling air inlet 220 can be reduced, and when the booster fan supplies air next time, the number and the air outlet positions of the unidirectional boiling air inlets 220 may be different, thereby achieving the boiling effect, reducing the possibility of accumulation, and facilitating the conveying.

The materials in the boiling chamber 210 are pumped into the feeding bin 310 through the negative pressure exhaust pipe 211 to be fed under the action of the air compressor 311, so that almost no dust is raised during material conveying, and the environment is protected.
