Background

Aluminum is a silver white light metal and is ductile. Commercial products made from aluminum are often in the shape of columns, rods, sheets, foils, powders, ribbons, filaments, and the like. Aluminum forms an oxide film on its surface in humid air to prevent corrosion of the metal. The aluminum powder treated with acid burns violently by heating in air and emits a dazzling white flame. The application of aluminum is very wide, and the recovery of waste aluminum products is an important part in the treatment of renewable resources. Because of the unique properties of aluminum and its alloys, it is widely used in three important industries, namely aviation, construction and automobile. One of the pretreatment purposes of the scrap aluminum is to remove other metals and impurities mixed in the scrap aluminum, iron and iron alloy are harmful impurities in the aluminum and the aluminum alloy, and the influence on the performance of the aluminum and the aluminum alloy is the greatest, so the waste iron and steel mixed in the pretreatment process should be sorted to the maximum extent.

However, the surface of the aluminum product is usually covered with a coating layer, so other common metal impurities, such as iron, copper or stainless steel, are usually mixed in the aluminum product, and are not easily distinguished, and the renewable resource recycling station usually recycles the aluminum product by a manual observation and sorting method, which is not favorable for batch recycling of the aluminum product due to low efficiency and low feasibility. Traditional recovery processing equipment can not carry out the breakage to aluminium scrap and reduce, and is more occupation space, handles inconveniently, and staff's later stage removes more troublesome, reduces work efficiency, and the messenger process of giving people has brought certain influence.
