    • Non-magnetic metal particles are separated from a mixture by an inclined rotating electrically insulating drum and the action of travelling electromagnetic field. The mixture is introduced at the upper end of the inclined drum which is supported by a rotary iron core through support rods. The rotary iron core and drum are rotated in one direction. Simultaneously, a shifting electromagnetic field is generated along the lower part of the outer periphery of the drum in a direction opposite to the direction of rotation of the drum. As a result, the mixture as it travels through the drum is repeatedly brought upwardly in the direction of drum rotation along the inner surface of the drum due to the frictional force between the mixture and the drum inner surface or upwardly in the direction of the shifting electromagnetic field and then tumbled down onto the bottom of the drum. This process provides a complete stirring of the mixture and promotes the separation of the non-magnetic metal particles irrespective of relative particle sizes.
    • 非磁性金属颗粒通过倾斜旋转电绝缘鼓和传播电磁场的作用与混合物分离。 该混合物被引入倾斜鼓的上端,该倾斜滚筒由旋转铁芯通过支撑杆支撑。 旋转铁芯和滚筒在一个方向上旋转。 同时,沿着与鼓的旋转方向相反的方向沿着鼓的外周的下部产生移动的电磁场。 结果,当混合物行进通过滚筒时,由于混合物和鼓内表面之间的摩擦力或沿着移动方向向上的方向,沿鼓的内表面沿滚筒方向重复地向上 电磁场,然后翻滚到鼓的底部。 该方法提供混合物的完全搅拌并且促进非磁性金属颗粒的分离,而不管相对粒度如何。

    • Disclosed is a process for melting aluminum alloy scraps which comprises the steps of: giving a rotation force to molten metal reserved in a cylindrical chamber so that the molten metal is made swollen up along the inner circumferential surface of the cylindrical chamber by a centrifugal force caused by the rotation force while the liquid-phase surface of the molten metal is kept so as to draw a parabola to thereby produce a vortex flow in the molten metal; and introducing aluminum alloy scraps into the vortex flow. Further disclosed is an apparatus for melting aluminum alloy scraps which comprises: a furnace body; a melt-material introduction portion having a cylindrical shape and being provided in the furnace body so as to communicate with the furnace body so that molten metal in the furnace body circulates to flow into the melt-material introduction portion; and a moving magnetic field generator provided along the outer wall of the melt-material introduction portion so as to cover the outer wall of the melt-material introduction portion.
