Eddy Current Seperators

Eddy Current Separators (ECS) are designed to separate non-ferrous conducting metals.

KW Supply Magneet systemen offers the following types and options:


Eddy Current Separators are increasingly used wherever separation of non-ferrous metals from a product stream can give a more valuable end product.

Whether the end use is in recycling, waste reduction, raw material production and any other process where separation would prove beneficial.

Typical examples of applications are:

  • Separation of non-ferrous metals in auto shredder residue.
  • Separation of non-ferrous metals from solid waste incinerator ash.
  • Sorting of steel and aluminium beverage cans.
  • Removal of contamination from crushed glass cullet.
  • Removal of non-ferrous metals from shredded wood.
  • Separation of non-ferrous dross from foundry sand.
  • Non-ferrous metal removal in WEEE recycling plants.
  • Separation of non-ferrous metals from Material Recycling Facilities.

Common Design Features

All of the KW Supply Magneetsystemen ECS units are built to combine the highest separating ability with a long and trouble-free operating life.

KW Supply Magneetsystemen ECS units are all manufactured using a concentric rotor design to allow for maximum separation over the entire outer drum face. This ensures that particles, which may be released through material free fall can also be separated, making it more efficient than the eccentric design.

The rotors used on the KW Supply Magneetsystemen range of ECS units are all dynamically balanced at 3600 RPM to ensure a trouble free operating life, even at the highest operating speeds.

Abrasion resistant PVC belts are used on the ECS units and to further improve the separation capabilities of the Eddy Current, they are specially designed to be very thin, minimising the gap between the product and the rotor.

The epoxy resin cover, which protects the rotors magnet system is also specially designed to be as thin as possible, whilst still giving the required strength. The cover has a blue outer layer and a clear under layer which, acts as a wear indicator.

To increase the performance of our ECS units and enable optimum separation, KW Supply Magneetsystemen offer optional vibratory feeders for spreading the material evenly across the ECS belt conveyor and producing what is known as a ‘mono-layer’.
