FIELD: metallurgy industry. ^ SUBSTANCE: invention refers to ferrous metallurgy. The line consists of system for extracting oxidised iron-bearing material from industrial waste and brickets forming system containing capacity for receiving raw material, which are installed with the possibility of interaction, mixing device and bricket forming device made in the form of vibrating press, and supplying, dosing and transportation mechanisms connected to each other. System for extracting oxidised iron-bearing material from industrial waste consists of supply silo and screening device, which are installed in series and connected by means of supply and transportation mechanisms. Screening device is connected with transportation mechanisms to dry magnetic separation plant and to hydrodynamic classification plant containing the following, which is installed in the direction of technological process and connected by means of transportation mechanisms: screw mixer, spiral separator and dehydration mechanism made in the form of band vacuum filter; at that, both plants are installed with the possibility of interacting with capacity receiving raw material of bricket forming system. ^ EFFECT: invention ensures return of iron-ore preparation waste to metallurgic production in the form of a bricket with increased content of iron oxides easy reduced in blast-furnace conditions. ^ 5 cl, 1 dwg |
