[0065] Optimally, the medium powder processing branch 5 further comprises a medium powder hopper 56, a medium powder conveying air pipe 57 and a medium powder fan 58.

[0076] The middle powder rack 59 divides the middle powder processing branch 5 into two layers, and the secondary crushed middle powder and iron can be collected by gravity, and the vertical space of the plant is reasonably utilized. Specifically, the middle powder conveying belt 51 continuously conveys the middle powder to the secondary crushing device 53 from bottom to top; the secondary crushing device 53 only needs to crush the middle powder twice, which can meet the subsequent use of the middle powder.

[0079] Since the fine powder is output below the two-stage screen 32 of the two-stage vibrating screen 3, the fine powder can be directly output to the fine powder conveying belt 61 through the fine powder output conduit 64 by gravity, and the fan structure arranged in the fine powder output conduit 64 can be omitted.

[0085] The output end of the fine powder iron removal moving mechanism 621 is movable, and can drive the fine powder iron removal electromagnet 622 to move back and forth between the conveying end of the fine powder conveying belt 61 and the fine powder iron removal container 623; meanwhile, the fine powder iron removal electromagnet 622 is an electromagnet, and has magnetic force in the energized state, which can adsorb iron in the fine powder on the fine powder conveying belt 61 at the fine powder conveying belt 61; after a certain time, the fine powder iron removal moving mechanism 621 drives the fine powder iron removal electromagnet 622 to move from the fine powder conveying belt 61 to above the fine powder iron removal container 623, at this time, only the fine powder iron removal electromagnet 622 needs to be powered off, so that the adsorbed iron can be output to the fine powder iron removal container 623, achieving the iron removal function.
[0086] The fine powder iron removal moving mechanism 621 is a mechanism known to have a driving moving function, for example, a combination of a gas cylinder, an oil cylinder, a motor and a screw rod, a conveyor belt structure, etc., as long as the movement of the fine powder iron removal electromagnet 622 is realized.
