IDEMAG is a magnetic system manufacturer and supplier of all kinds of magnets.

EDDY CURRENT SEPARATOR

IDGSM metal separators are designed for the selection and elimination of non-ferrous metals by the eddy currents.

OVERBAND MAGNETS

The Overband placed suspended above the band that transports the material to be filtered. Its operation can be transverse or parallel to the existing installation.

OPERATION.

Eddy Current separation system consists of a conveyor belt and a rotor with a magnetic circuit built in 14 or 24 poles; to adapt to the grain-size distribution of the product. All within a steel case and covered by a counter drum . Being separates, the drum and the rotor inductor, allows operation at different frequencies. When the rotor turns at high speed it generates an electric current in the conductive metals (nonferrous), this inductive voltage produces a magnetic field opposite to the rotor, causing the non-ferrous metals being repelled. The rejected metal falls into the hopper by gravity, being separated from the other material.

APPLICATIONS.

Eddy Current separators are indicated for the separation of non-ferrous metals: aluminum, brass, copper, etc., from inert materials. Used by recyclers in various sectors, production of semimanufactured and other processes.

Typical examples:

· Separation of nonferrous metals in: car crushers, foundry slag, foundry sand, debris in domestic and industrial recycling companies, recycling plants.
· The selection of soda cans in a stream of dry recycling.
· Withdrawal of non-ferrous metals from crushed wood or glass.
· Withdrawal of aluminum components in recycling plastic frames.

GENERAL.

All metal separators supplied by IDEMAG are manufactured to have optimal performance and maximum operational life.

IDGSM systems have been developed with concentric rotors for a high separation capacity of the whole drum surface, allowing the particles released during the “free fall” also to be separated. To improve the capacity the separator is manufactured with wear resistant conveyor belts, made in high quality PVC.

These belts, extremely thin, are specifically designed to minimize the distance between the rotor and the material to be separated. For the same reason, the rotor housing has also been made “as thin as possible”, without lowering the mechanical power.

Additionally, to improve Eddy Current separator performance, our company can supply matching vibrating tables.

The Overband placed suspended above the band that transports the material to be filtered. Its operation can be transverse or parallel to the existing installation. The drive can be by a hydraulic motor or an electric motor.

The power of the drive motor depend on the length of overband, the material to be filtered and the speed of the conveyor. Whether to mount an electric or pneumatic depending on the installation environment will be assessed. Our department expects each unit depending on customer needs.

MAGNETIC DRUM

The stationary magnetic assembly inside the unit’s shell captures tramp metal as the material flow into the drum. With contaminants removed, the good product falls freely to a discharge point. As the drum rotates, cleats sweep the ferrous debris through and out of the magnetic field as the drum rotates. The tramp metal is discharged separately thereby creating continuous self-cleaning separation.

MAGNETIC HEAD

Magnetic heads designed for the palletization and de-palletization of empty cans and aerosols, filled and closed steel cans or filled glass jars with steel twist caps.Magnetic palletizers make use of permanent magnets, so no power is required, a layer of products remains hanging as long as necessary.
