The present invention relates to an apparatus for separating and collecting metal scrap which can effectively separate and collect metal scrap from industrial waste.

In general, metal scrap (metal scrap) is generated as a by-product when making a metal product in the industrial field, a general term for the waste of the metal product or metal material and can be recycled. In particular, metal scrap becomes a raw material of steel. In the manufacture of metals other than steel, scrap is an important raw material. In the case of mixing and dissolving raw metals to make whole body materials such as plates, rods, and pipes, the cutting scraps generated when these body materials are made, that is, scrap, are cut to a specified limit. It is common to add to the raw materials. When making castings, raw materials often contain a significant amount of scrap.

The recovery device for metal scrap is required to be at least compatible with the production device for producing such metals, and for this purpose, it is effective that the recovery device is designed to recycle a certain or specific type of metal scrap. Particularly in the field of light metals such as aluminum, scrap that occurs early in the manufacturing process is mainly generated during the pretreatment of the surface of aluminum, which is a significant amount of 6% of the total metal in the ingot. Recycling metal scrap provides ecology.

On the other hand, since the metal scrap is literally scrap metal, the more it is compounded, the lower the economic added value, and thus its use is limited. Since castings are tolerant of the amount of impurities, many scraps can be used, and in the case of iron, a considerable amount of debris from various iron products can be blended. In order to use scrap effectively, it is important to manage it according to the material and the degree of contamination.
