In the metal recycling sector, managing scrap composed of aluminum and iron requires solutions capable of transforming heterogeneous materials into clean, homogeneous, high-value fractions.
Among the most efficient and versatile machines is the hammer mill, used in processing plants for ferrous and non-ferrous scrap coming from demolitions, automotive dismantling, electronics and manufacturing industries. The hammer mill not only reduces the size of the scrap but also represents the key step that enables proper separation of ferrous and non-ferrous metals.
Iron and aluminum are found in numerous components such as engines, radiators, heat exchangers, appliances and end-of-life vehicles.
The separation of iron and aluminum is a crucial phase in the recycling process for several reasons.
From an economic standpoint, the two metals have very different market values: clean aluminum can reach significantly higher prices, while iron requires accurate classification before it can be sold to steel mills. Separating them allows the production of secondary raw materials of higher-quality.
Purity is also essential: foundries require metals with minimal impurities because a mixture of iron and aluminum would compromise both the mechanical properties and the quality of the resulting alloys, furthermore, the two materials are not mixable. In fact, the two metals have very different melting points (iron above 1,500°C, aluminum around 660°C), so proper separation makes the melting process more efficient and cost-effective.
From an environmental perspective, recycling pure aluminum saves up to 95% of the energy required for primary production—an enormous benefit achievable only if the material is correctly separated.
The Hammer mill TAURUS MINIMILL plays a key role because it prepares the scrap for the separation phase. Thanks to its anvil, MINIMILL can break extremely tough materials that hammers alone could not process. The result is a more uniform and compact product, with a controlled particle size, ideal for subsequent separation.
After the shredding phase, the material is conveyed to the magnetic drum, which attracts the iron and isolates it from the non-ferrous fraction. This produces a clean ferrous output, ready to be sent to steel mills for reuse in production processes.
The non-ferrous material is then fed into the eddy current separatorwhere a rotating magnetic field selectively repels non-ferrous metals, likealluminio, separandoli da plastiche, vetro e altri scarti. Il risultato è un alluminio pulito e valorizzabile dalle fonderie.
Hammers mill therefore remains essential in this process thanks to its high productivity , its ability to handle very different materials, and its consistent particle size. It produces a more homogeneous material, improves metal separation and increases the value of the recovered metals, while also reducing waste and environmental impact.
