If the magnetic of granulated blast-furnace slag Vertical Mill can be effluxed thing further purifies, iron compound is further recycled, will improve the added value of granulation blast-furnace slag greatly; avoid the wasting of resources; reduce environmental pollution, turn waste into wealth, good economic benefits and social benefit are arranged.
The utility model content
The purpose of this utility model provides a kind of novel vertical grinding machine outer circulation secondary magnetic separation system; this system can improve the rate of recovery that magnetic effluxes iron content in the thing greatly, effectively improves the added value of granulation blast-furnace slag, avoids the wasting of resources; reduce environmental pollution, turn waste into wealth.
For achieving the above object, the utility model is achieved through the following technical solutions:
Novel vertical grinding machine outer circulation secondary magnetic separation system comprises two-stage magnetic separation system, and first order magnetic separation system comprises first order vibra feeder and first order tramp iron separator, is successively set on grinding machine outer circulation loop bucket elevator and goes out between material level and the grinding machine; Second level magnetic separation system comprises second level vibra feeder and second level tramp iron separator, second level vibra feeder is connected by the secondary magnetic separation pipeline with first order tramp iron separator, second level vibra feeder is connected with second level tramp iron separator, and tramp iron separator connection in the second level effluxes conduit.
Described second level tramp iron separator also is connected with grinding machine bottom chute by the feed back pipeline.
The described conduit connection magnetic that effluxes effluxes the thing warehouse, and magnetic effluxes to be provided with in the thing warehouse magnetic is effluxed the diagrid that thing carries out grading.
Described secondary magnetic separation pipeline is provided with by-pass valve control.
Compared with prior art, the beneficial effects of the utility model are:
Adopt the method for repeatedly magnetic separation; having solved vertical grinder effluxes the magnetic separation thing to contain ferrous components not high; problem that can not be recycling; the former iron content rate that effluxes thing that is magnetic is increased to about 97% by original 10%-11%, make the utilization of granulated blast-furnace slag more effective, simultaneously the powder after the magnetic separation be returned grinder system; reduced product losses; reduce on-the-spot dust pollution, realized zero-emission, had very big economic benefit and social benefit.
