A single breed of waste aluminum
This kind of waste aluminum is generally a kind of waste parts, such as the piston of the internal combustion engine, the car's deceleration casing, the wheel hub, and the car front and rear safety bolts.Aluminum doors and Windows.These aluminum waste products have been classified and have a single variety and are imported in bulk. Therefore, they are high quality recycled aluminum raw materials.
Waste aluminum slices
Waste - mixed aluminium slices are also shortened to be sliced, which is a higher grade of waste aluminum.Are called slices, because in many developed countries in dealing with automobiles, equipment and all kinds of waste household appliances, all adopt the method of mechanical dance to break it into broken material, and quality of waste aluminum slice more expensive than other aluminium scrap prices, to adapt to the large-scale modern enterprise, and difficult to ends up in the international market, so our country besides wholly owned or joint venture imports, general regenerative aluminium factory seldom use this kind of waste.The separation of aluminum is the waste aluminum section.In addition, the recycling department also USES broken methods to break up some of the larger pieces of aluminum scrap, which are also called scrap aluminum slices.The waste aluminum section is convenient to transport and easy to select, and the texture is pure, which is also high quality waste aluminum.At present, in the international market of waste aluminum trade, slice of the largest amount, all kinds of slices forward standardized development.In terms of sliced ingredients, generally can be divided into several class, one of the high class section are relatively pure a mixture of all kinds of scrap aluminum and its alloy, for the most part without any treatment can be charging smelting, a small amount of the grade lower slice containing different amounts of other impurities, containing aluminium scrap again by 80% - more than 90%, when the main impurity such as iron and steel scrap and copper scrap non-ferrous metals, also contains a small amount of waste rubber, etc., after artificial selection, pure aluminium scrap material.Smelting aluminium scrap slice is easy, convenient smelting when charging, removing impurity easily, less solvent consumption, high metal recovery, low energy consumption, processing cost is low, is very popular with users, general large regenerative aluminium factory were to slice as the main raw material.
High quality aluminium scrap slice more expensive than other aluminium scrap prices, to adapt to the large-scale modern enterprise, and difficult to ends up in the international market, so our country besides wholly owned or joint venture imports, general regenerative aluminium factory seldom use this kind of waste.
A mixture of waste aluminum
Such miscellaneous scrap aluminum composition is complicated, a variety of shapes and physical except miscellaneous scrap aluminum, also contains a certain amount of iron and steel scrap, scrap metals such as lead, zinc scrap and waste rubber, waste wood, waste plastics, stone, etc., sometimes part of the scrap aluminum and scrap machine together, such waste composition is complicated, a small amount of aluminium scrap, more surface clear, and easy separation.This kind of waste must be pre-selected and processed before smelting, which is to manually select scrap steel and other impurities.
The burnt aluminum scrap aluminum
This aluminum material is a low grade aluminum waste, mainly a variety of scrap household appliances and other pulverized materials, sorted out a part of scrap steel and then burned into the material.The purpose of incineration is to remove combustible materials such as waste rubber and waste plastics.The aluminium content of this type of aluminum waste is about 40 percent -- about 60 percent, and the rest is mainly non-ferrous metals such as garbage (brick blocks), scrap steel, and extremely small copper (copper wire).Aluminum blocks under 10 centimeters commonly, in the process of burning, aluminium and low melting point of the material such as zinc, lead, tin melting, and other materials formed on the surface of glass material, to the naked eye is difficult to distinguish, not separation.
A mixture of crushed aluminum
This kind of waste are the lowest grade aluminium scrap, its composition is very complicated, which contains all kinds of aluminium scrap in 40% - 50%, the rest is the iron and steel scrap, a small amount of lead and copper, a lot of garbage, stones and earth, waste plastics, waste paper, such as soil accounts for about 25%, scrap 10% - 20%, stones of 3-5%.
