In addition, since the converter slag has a decay property, the modifiers such as SiO 2 , Al 2 O 3 , Fe 2 O 3, and the like are added to the slag and then put into a primary crusher. Next, the slag crushed by the primary crusher is placed in the secondary crusher 1 as shown in FIG. 2 and here, the dead product discharged through the hole 3 of the grating member 2 as shown in FIG. Distinguish between (M 1 ) and casualties (M 2 ) that do not go through the government.

사하물(M1)은 관공(3)에 의해 소정의 입경으로 분급 파쇄되어 있으나, 이 사하물(M1)을 더욱 균일한 입경으로 파쇄하기 위해서 제4도에 나타낸 것과 같은 3차 파쇄기(4)에 옮겨 작은 입경으로 분급 파쇄하고, 이 사하물(M3)을 분별장치에 넣어, 여기서 지그(Jig) 또는 테이블 콘센트 레이터(Table Concentrator) 등의 장치에 걸어 비중선광을 행하여 금속분과 불순물로 분리하고, 이어서 이 불순물은 자선기에 옮긴다. 또한 상기한 2차 파쇄기(1), 3차 파쇄기(4), (통상은 습식이 좋다). 또한, 분별장치의 도중에서도 니켈, 크롬, 철을 포함한 지금이 회수되기 때문에, 이 회수물(M4)을 처리하여 니켈과 같은 고가한 금속을 회수한다. 또한 자선기에 옮겨진 금속물을 많이 포함한 불순물은 여기서 자착물과 비차착물로 자선된다. 철, 니켈은 자착물로서 회수되고, 크롬은 비 자착물로서 회수된다. 또한 니켈을 많이 함유한 스텐레스강도 자착물로서 회수되기 때문에, 상기 자착물로부터 고가한 니켈분을 분별하여 회수할 수 있는 것이다. 그리고, 자선기에서 금속물이 분취된 나머지의 잔여물은 별도 회수되어 매립이나 아스팔트 공사의 바라스재등으로 사용되는 것이다.The dead object M 1 is classified and crushed by the hole 3 to a predetermined particle size, but in order to crush the dead object M 1 to a more uniform particle size, a tertiary crusher 4 as shown in FIG. ) And classify and shred it into small particle diameters, and put this dead object (M 3 ) into a separator, where it is suspended in a device such as a jig or a table concentrator and subjected to non-negotiation to separate it into metal powder and impurities. The impurities are then transferred to the charity. In addition, the above-mentioned secondary crusher 1, tertiary crusher 4, (wet is generally preferable). In addition, since the now containing nickel, chromium, and iron is recovered even in the middle of the fractionating apparatus, this recovered product M 4 is treated to recover expensive metal such as nickel. In addition, impurities containing a large amount of metal transferred to the charity are charitable here as non-fixed matter. Iron and nickel are recovered as dead substances and chromium is recovered as non-dead substances. In addition, since stainless steel containing a large amount of nickel is also recovered as a magnetic substance, expensive nickel powder can be separated and recovered from the magnetic substance. Then, the remaining residue from which the metal is separated from the charity is collected separately and used as a barast material for reclamation or asphalt construction.
