Magnetic Systems in Rubber Recycling

Rubber recycling is an essential practice for environmental sustainability, as it contributes to the reduction of greenhouse gas emissions and helps to slow the weakening of the ozone layer. It also prolongs the life cycle of the material and allows its reuse in various applications, such as playground pavements, drainage, building fillers, water ponds, acoustic screens, road asphalt, shoe soles, barriers, artificial grass and new tires.

Recycled rubber is suitable for both indoor and outdoor use due to its impact resistance and its ability to absorb noise. However, its reuse must guarantee the elimination of any contamination, especially metals, which could compromise its safety and quality. To achieve pure and safe recycled rubber, it is essential to use magnetic separation systems.

Magnetic Separation Systems in Rubber Recycling

Recycled rubber is usually processed in powder form, so it is crucial to remove small wire fragments and other metal impurities before reuse. For this purpose, different types of magnetic separators are used to ensure efficient removal of metal contaminants.

Neodymium Magnetic Plates

When recycled rubber is fed into a powder crusher, a magnetic separator capable of removing small metal particles is required. Neodymium magnetic plates are ideal for this process, as they allow the capture of extremely fine metal contaminants.

Overband Magnets

If the metal particles are larger in size and exceed 1 mm, overband magnets are an effective solution. Available in permanent or electromagnetic field versions, these magnets are widely used in rubber processing due to their reliability and cost-effectiveness. Overband magnets are easily installed on conveyor belts and require few adjustments on production lines.

Benefits of Magnetic Separators

Magnetic separators are designed in different formats, qualities and sizes, with the aim of automatically or semi-automatically removing metal particles and iron oxide. This allows to guarantee the safety and quality of the product in the following phases of the production process.

Among the most common magnetic separation products are:

Magnetic bars

Magnetic grids or filters

Magnetic separators with removable drawer

Rotating magnetic separators

Magnetic plates

Magnetic rollers

Conclusion

The use of magnetic systems in rubber recycling is essential to guarantee the purity of the material and its safety in future applications. By efficiently removing metallic impurities, these systems allow recycled rubber to maintain its resistance, cushioning and noise absorption properties. In addition, their implementation in recycling lines improves production efficiency, optimizes resources and contributes to a positive environmental impact. In this way, rubber recycling becomes a sustainable and functional solution for numerous industries and applications.
