Sud Recycling offers a comprehensive range of specialized equipment for the purposes of magnetic metal separation, as well as eddy current and electrostatic separation.
These machines – called sometimes also overbelt Separators – consist essentially of a magnet (electro- or permanent one) around which a belt called extracting band turns.
Static Electro Magnetic Separator
The protection electromagnets EP and the permanent magnet plates (SMP) are static equipment for iron separation: their purpose is to extract iron particles from a flow of inert material holding it tightly till the operator carries out its detachment.
Electro Magnetic Pulleys
The electromagnetic and permanent magnet pulleys are usually mounted as end rollers on conveyors. Their aim is to hold ferromagnetic intrusions present in the process material and discharge them automatically in the point the conveyor leaves the roller on its return way.
Electro Magnetic Drums
Magnetic drums are essentially made of a static magnetic circuit and a not-magnetic rotating cylindrical housing. Their fundamental aim is to attract the ferrous intrusions in the inert material, hold them on the cylindrical housing surface. While inert material falls naturally, the intrusions are discharged only when the housing goes outside the influence of the static magnetic field.
The tubular magnetic filters are magnetic separators which, inserted vertically by the fall of granulose or pulverized material, attract and hold the contained ferrous parts leaving clean inert. These filters are particularly suitable to stop accidental ferromagnetic intrusions, whose presence worsens the product quality or jeopardizes downstream machines.
Magnetic Drum Separation
The main aim of the TMR separator is to separate particles with medium/low magnetic susceptibility from inert non magnetic material.
EDDY CURRENT SEPERATOR – Non Ferrous Metals Separator
The separator for non-ferrous metals ECS is based on the induced (Foucault) currents generated by a rotating magnetic field. The currents induced in the metal brings to a repulsion force able to expel the metal from the inert material flow.
ELECTRO STATIC SEPERATION
The electrostatic method separates particles of different electrical charges and, when possible, of different sizes. When particles of different polarity are brought into an electrical field, they follow different motion trajectories and can be caught separately. Electrostatic separation is used in all plants that process heavy mineral sands bearing zircon, rutile, and monazite.
Some examples of the use of electrostatic separators:
- recovery of light fractions precious metals (gold, silver, palladium) in the recycling of PCB boards, E-scrap and Weee
- recovery of light fractions of metals (copper and aluminum) from the plastic fraction of the recycling operations of cables and electrical wiring
