SMVT eddy current magnetic separators

SMVT eddy current magnetic separators

SMVT eddy current magnetic separators are designed to recover nonferrous inclusions from non-conducting materials.

Material is fed on the separator’s vibratory feeder where it is uniformly transported to the belt conveyor, which drive drum contains integrated magnetic rotor (conveyor and magnetic rotor are activated by separate drives). When the material flows on the drive drum surface in a close proximity to the magnetic rotor rotated at high speed, electromotive force is activated by alternate magnetic rotor field in nonferrous inclusions and eddy currents occur. As a result of interaction of magnetic fields created by eddy currents with the rotor’s magnetic field, the trajectory of nonferrous metals inclusions is changed – they are “thrown away” from the non-conducting flow and discharged into a separate outlet of the separator.

SMVT eddy current separators are actively applied both in recycling facilities and enterprises, using own or purchased secondary raw material – steel works, glass factories, etc.

  • Vibratory feeder ensures uniform distribution of material flow at the whole width of the separator’s working area.
  • Electronic frequency converters used to control conveyor belt speed and magnetic rotor speed ensure continuous setting of operation modes of SMVT separators for their maximum efficiency.
  • Depending on specific separation (sorting) tasks, SMVT eddy current separators are produced with eccentric or concentric location of magnetic rotors relative to the drum axis.
  • Unique patented magnetic systems on permanent magnets ensure long effective operation of magnetic separators. The warranty retention life of magnetic system features, if the operation conditions are observed, is 10 years.

Strong-magnetic inclusions should be removed from separation materials before eddy current magnetic separators. SMPR and SMPA suspended guard magnets, SMB pulley guard magnets or compact BSM drum separators are traditionally applied for this purpose.
