Suspended guard magnets of SMPA, SMPA-M and SMPA-TM series

Suspended guard magnets of SMPA, SMPA-M and SMPA-TM series

Powerful self-dumping suspended guard magnets with mechanical treatment system ensure qualitative removal of large strong magnetic inclusions from material flows transported by belt conveyors.

Material transported by a conveyor enters in the magnetic field area of the guard magnet, under the effect of which strong magnetic inclusions, locating in the material flow, are drawn to the guard magnet and held at a surface of rubber-fabric belt magnetic system rotating around it. Metal inclusions are dumped during their traveling outside the limits of the magnetic field by dumping ribs fixed on the belt.

Research and Production Company “ERGA” produces self-dumping suspended guard magnets of SMPA series (with ‘standard’ magnetic systems), SMPA-M (with more powerful magnetic systems) and SMPA-TM series (comparable with electromagnetic guard magnets by their power). Self-dumping suspended guard magnets not requiring frequent attention from service personnel, are often applied in automatic and automated lines.

  • The depth of removal area is one of the main quality parameters of suspended guard magnets. Unique magnetic systems designed by Research and Production Company “ERGA” ensure the removal of strong magnetic inclusions from the distance up to 450 millimeters from the operating surface of the guard magnet!
  • Unique patented magnetic systems on permanent magnets ensure long effective operation of guard magnets. The guaranteed retention life of magnetic system features as long as operation conditions are observed is 10 years.
  • Thanks to the magnetic systems on permanent magnets, SMPA and SMPA-M and SMPA-TM guard magnets do not consume electrical power to generate a magnetic field and differ from their electromagnetic equivalents by the considerably higher operational reliability.
  • Suspended self-dumping guard magnets produced by Research and Production Company “ERGA” correspond to current requirements of industrial safety regulations and rules in the Russian Federation and can be applied in explosive and flammable, chemically hazardous productions and facilities.

Guard magnets of SMPA-TM series are intended for operation in extremely difficult conditions – due to the powerful magnetic systems, they are capable to remove especially large metal inclusions with the weight up to 40 kg from material flows the and provide effective recovery even at a high speed of material transportation (with belt speed to 3 m/s).
