Claims (5)

1. Способ переработки шлака, включающий предварительную выборку крупного металлического скрапа, стадийное дробление материала с последовательным отбором металла на каждой стадии посредством рассеивания на перфорированной поверхности, магнитной сепарации или ручной выборки металла и воздушной сепарации, отличающийся тем, что воздушную сепарацию проводят на каждой стадии после дробления посредством перемещения материала в потоке воздуха, обеспечивая извлечение пылевидной фракции наименее плотной неметаллической составляющей смеси, после чего осуществляют магнитную сепарацию материала или ручную выборку металла, после заключительной стадии дробления перед воздушной сепарацией проводят избирательное измельчение неметаллической составляющей материала, при этом в процессе переработки обеспечивают постадийный перевод всей неметаллической составляющей перерабатываемого материала в пылевидную фракцию и извлечение ее потоком воздуха.1. A method of processing slag, including preliminary sampling of large metal scrap, stage-by-stage crushing of material with sequential selection of metal at each stage by scattering on a perforated surface, magnetic separation or manual sampling of metal and air separation, characterized in that the air separation is carried out at each stage after crushing by moving the material in the air stream, ensuring the extraction of the pulverulent fraction of the least dense non-metallic component of the mixture, after which magnetic separation of the material or manual sampling of the metal is carried out, after the final stage of crushing before air separation, selective grinding of the non-metallic component of the material is carried out, while in the process of processing, the entire non-metallic component of the processed material is stage-by-stage converted to a dust fraction and extracted by an air stream. 2. Способ по п.1, отличающийся тем, что перед стадийным дроблением материал сушат.2. The method according to claim 1, characterized in that before the stage crushing, the material is dried. 3. Способ по п.1, отличающийся тем, что воздушную сепарацию на заключительной стадии осуществляют в корпусе воздушных сепараторов с вращающимися билами, с помощью которых в процессе воздушной сепарации разбивают спрессованный измельченный материал.3. The method according to claim 1, characterized in that the air separation at the final stage is carried out in the casing of the air separators with rotating blades, with the help of which the pressed crushed material is broken in the process of air separation. 4. Способ по п.1, отличающийся тем, что на всех стадиях в процессе воздушной сепарации регулируют температуру и влажность воздушного потока.4. The method according to claim 1, characterized in that at all stages in the process of air separation regulate the temperature and humidity of the air stream. 5. Способ по п.1, отличающийся тем, что избирательное измельчение неметаллической составляющей осуществляют в валковой мельнице, при этом для измельчения предварительно отбирают фракцию меньше 0,01 Dвал., где Dвал - диаметр валков. 5. The method according to claim 1, characterized in that the selective grinding of the non-metallic component is carried out in a roller mill, while a fraction of less than 0.01 Dval is preliminarily selected for grinding, where Dval is the diameter of the rolls.
