LINE FOR PREPARING MOIST IRON-CONTAINING SLIMES OF METALLURGICAL PRODUCTION FOR AGGLOMERATING

摘要

The invention relates to the utilization of small fraction metallurgical wastes, namely iron blast furnace and BOF sludge production and can be used in metallurgy and construction materials. The basis of the utility model, the task of improving the line for the preparation of iron-containing wet sludge to the agglomeration of metallurgical production by expanding its technological capabilities through the introduction of its new units, providing a high degree of concentration of sludge of metallurgical production. This increases the content of iron oxides and reduces the amount of ballast and harmful impurities in the mixture to agglomerate or briquette molding. The use of the material obtained in the production of the agglomerate or briquette introduced as additives into the batch during production of iron, will bring out the charge of the purchase of pellets and savings iron, carbonaceous feedstock. The problem is solved in that the line for preparing moist iron sludges metallurgical industry for agglomeration in part arranged in series on the downstream side for engagement means screening, enrichment and dewatering sludge according to the utility model, further comprises a set of downstream from the screening media, thickener and shlamonasos and sludge enrichment means comprises a series arrangement mo plants cut of magnetic separation and hydrodynamic classification formed as helical gateways, each of which is connected to the dewatering means arranged to cooperate with a mixer for receiving and mixing iron-containing material which is connected a supply of material to one or more capacity for blast furnace dust and / or aspirating dust Limekiln workshops, and / or electrostatic dust blast furnace shop. Furthermore, the line as dewatering mechanism comprises a vacuum filter, and as the screening means comprises a crashing cone, and as the installation comprises a screw hydrodynamic classification gateways. 3 p.
