Metal recycling: efficient processes and solutions

Metal recycling is a strategic pillar of the circular economy and the optimization of industrial resources. Our approach focuses on transforming metal waste into reusable raw materials using robust, high-performance technologies. From sorting and size reduction to material separation and cleaning, our lines are designed to maximize the purity of the recovered metal, reduce operating costs, and ensure continuous operation in demanding environments.

We work with metal recycling companies and industrial plants that need to process large volumes of waste reliably and precisely. Therefore, we integrate equipment such as shredders, granulators, and peripheral separation systems tailored to each type of material and production objective.

How to process and valorize waste from metal?

The proper processing and valorization of metal waste is essential to maximize material recovery, reduce operating costs, and ensure efficient and sustainable recycling. At Silmisa, we approach this process holistically, applying industrial technology designed to treat large volumes of metal waste with high levels of precision and reliability.

The valorization of metal is not limited to reducing its size; it involves proper classification, separation and conditioning of the material so that it can be reintroduced into the production chain with the highest possible value.

Classification of industrial metal waste

The first step towards effective recycling is sorting metal waste according to its composition, size, and origin. Industrial plants often contain mixed waste that requires prior separation to optimize the process.
In this phase, materials such as ferrous and non-ferrous metals, metallic waste from cables, industrial parts, and light scrap metal are identified and classified...

Effective management of metal waste

Once sorted, the waste moves to an efficient metal waste management phase where technology plays a crucial role. At Silmisa, we design lines that integrate: shredders and granulators for controlled size reduction, magnetic separators and peripheral systems to remove impurities, and conveying and sorting equipment that ensures a continuous flow of material.

Types of waste metallic and his recovery

Metal recycling encompasses a wide variety of materials from different industrial sectors. Correctly identifying the type of metal waste is essential to applying the appropriate process and maximizing its recovery and economic value. At Silmisa, we develop specific technology to treat each type of metal, guaranteeing efficient separation and high purity of the recovered material.

Non-ferrous metals: aluminum and copper

Aluminum wire

Recycling aluminum allows the recovery of a lightweight, resistant and 100% recyclable metal, significantly reducing energy consumption compared to primary production. Likewise, our machinery allows: controlled crushing and reduction of the material, efficient separation of impurities, and the production of clean and valuable aluminum.

Copper

Copper recycling is key to recovering metals from electrical cables, industrial components, and electronic waste. Its high value demands precise and reliable processes. Silmisa's technology achieves: efficient cable granulation, optimal separation between metal and insulation, and high purity of the recovered copper.

Crushers and granulators for metals

Metal shredders and granulators are at the heart of the metal recycling process. They reduce the size of the waste, separate the metal from other materials, and prepare the product for efficient separation.

At Silmisa we design shredders and granulators to work with metal waste such as:

  • Light scrap.
  • Electric cables.
  • Industrial profiles and parts.
  • Metallic mixtures with plastics or other materials.

Some of the main advantages of our equipment are:

  • High mechanical resistance for hard and abrasive materials.
  • Controlled size reduction avoiding material loss.
  • Continuous and stable operation, ideal for industrial environments.
  • Homogeneous granulation, key to improving subsequent separation.

Peripheral equipment for metal separation

To obtain high-purity metal, crushing and granulation must be complemented with peripheral metal separation equipment. At Silmisa, we integrate solutions that eliminate impurities and separate fractions with maximum precision.

Among the most common equipment, we highlight:

  • Magnetic separators (overband) for ferrous metals.
  • Suction systems and cyclones for removing light fractions.
  • Specialized conveyor belts that ensure a continuous and orderly flow of material.
  • Densimetric tables or other classification systems according to the type of waste.

These peripherals allow:

  • Increase the purity of the recovered metal.
  • Protect the main machinery from premature wear.
  • Mejorar la eficiencia y estabilidad del proceso.
  • Obtain a final product ready for valuation.
