摘要

#$%^&*AU2019100603A420190711.pdf#####11 ABSTRACT A processing device for dry grinding magnetite, comprising a first pressure adjustment bin (10), a roller press (20), a wind classification box (30), a dust collector (40), and a second pressure adjustment bin (50) and a plurality of dry magnetic separators (60). The feed inlet of the roller press is connected to the discharge end of the first pressure adjustment bin. The feed inlet of the wind classification box is connected to the discharge end of the roller press. The air inlet of the dust collector is connected to the air outlet of the wind classification box. The feed inlet of the second pressure adjustment bin is connected to the discharge end of the wind classification box. The feed inlets of the dry magnetic separator are connected to the discharge end of the second pressure adjustment bin, and the discharge ends of the concentrate from the dry magnetic separator are connected to the feed inlet of the first pressure adjustment bin. This embodiment provides a processing device that has high beneficiation efficiency with low energy consumption. This embodiment also provides a beneficiation process system using the above-described processing device.1/2 FIG 1 73 71 4 400 310 72 81 fine powder ore 50 pushed iroe ore 6020 tailings disposal system 85
