    • PURPOSE: An apparatus for separating needle-shaped slag from granulated ferronickel slag is provided to increase the eliminating efficiency of the needle-shaped slag by rapidly implementing a separating process. CONSTITUTION: An apparatus for separating needle-shaped slag from granulated ferronickel slag includes a housing(110), a first inlet(120), a second inlet(130), a first outlet(140), and a second outlet(150). The upper side of the housing is cylindrical. The lower side of the housing is composed of a conical-shaped cone part(111). A space is formed in the housing. A first inlet is vertically formed at the upper side of the housing, and granulated ferronickel slag is introduced through the first inlet. A second inlet is formed to the perpendicular direction of the upper side of the housing, and water is introduced through the second inlet. The first outlet is formed to the tangential direction of another upper side of the housing. Needle-shaped ferronickel slag is discharged through the first outlet. Remaining coarse ferronickel slag is discharged through the second outlet.
    • 目的:提供一种用于从造粒铁镍渣分离针状炉渣的设备,通过快速实施分离工艺,提高针状炉渣的消除效率。 构成:用于从造粒铁镍渣中分离针状炉渣的装置包括壳体(110),第一入口(120),第二入口(130),第一出口(140)和第二出口(150)。 外壳的上侧是圆柱形的。 壳体的下侧由圆锥形的锥形部分(111)组成。 在壳体中形成空间。 第一入口垂直地形成在壳体的上侧,并且造粒的铁镍渣通过第一入口引入。 第二入口沿着壳体的上侧的垂直方向形成,并且通过第二入口引入水。 第一出口形成为壳体的另一上侧的切线方向。 针状铁镍渣通过第一出口排出。 剩余的粗镍铁渣通过第二出口排出。

    • PURPOSE: A method for recycling ferronickel slag is provided to produce high specific gravity materials, which are possibly used as concrete materials, by separating non-magnetically attaching slag with low iron content from ferronickel slag. CONSTITUTION: A method for recycling ferronickel slag includes the following steps of: preparing ferronickel slag(S100); separating the ferronickel slag into magnetically attaching slag and non-magnetically attaching slag by primary magnetic classification(S200); pulverizing the separated non-magnetically attaching slag(S300); and separating the pulverized slag into the magnetically attaching slag and non-magnetically attaching slag by secondary magnetic classification(S400). The ferronickel slag includes 50-60% of SiO2, 30-40% of MgO, 0.1-10% of Fe2O3, 0.1-1% of NiO, and impurities. The average diameter of the ferronickel slag is 10mm or less. The magnetic intensity of the primary magnetic classification and secondary magnetic classification are in a range between 3 and 6kG.
