SMBM and SMBM-2 drum magnetic separators

SMBM and SMBM-2 drum magnetic separators

Self-dumping drum separators with pendulous flaps and guide -trays built in the hoppers, magnetic system position control and splitter adjustment provided in the housings.

Separation material goes through the hopper to the guide tray, uniformly distributing at its full width. Material is fed from the tray to the drum shell, rotating around the fixed magnetic system, creating powerful magnetic field in the separator’s working area. Under the effect of the magnetic field, strong magnetic inclusions in the material flow are attracted to the magnetic system and held on the shell surface rotating around it. Such inclusions are dumped during their movement outside the magnetic field area by rejecting ribs mounted on the shell.

SMBM drum separators are mostly applied for cleaning dry bulk materials from magnetic inclusions of different sizes (incl. from so-called rubbing, formed as a result of equipment wear), and are also used for ore beneficiation, slagheap processing and solution of other separation tasks, when the magnetic material component is valuable.

SMBM-2 large-size drum separators are designed for operation in heavy duty industrial conditions as part of high-capacity (50 – 300 t/h) process lines, they are successfully applied for the separation of fraction up to 80 mm.

  • Possibility to control the material flow with the pendulous flap and uniform material distribution on the guide tray, together with the possibility of magnetic system and splitter adjustment, ensure optimal conditions for magnetic separation.
  • MBM and SMBM-2 magnetic separators can be used for the operation with dusty materials - access covers and doors are equipped with seals, if required, the possibility of connection to the aspiration systems is provided.
  • Research and Production Company “ERGA” personnel have designed many different configurations of magnetic systems for SMBM and SMBM-2 drum separators. Thus, for example, depending on the magnetic susceptibility of materials and inclusions magnetic induction systems with the range of 100 to 900 mT are selected for SMBM separators, and the ones with the range of 100 to 600 mT are selected for SMBM-2 separators.
  • 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.
  • SMBM and SMBM-2 magnetic separators have a lot of advantages over their electromagnetic equivalents – no power consumption for the generation of magnetic field, higher operation reliability, smaller dimensions and lighter weight.
  • SMBM and SMBM-2 drum separators can be applied for the operation with abrasive materials – in such cases, housing and shell components contacting with materials are protected against accelerated wear with polyurethane lining or changeable protective stainless steel plates.
  • SMBM and SMBM-2 magnetic separators correspond to the requirements of industrial safety rules and regulations valid in the Russian Federation and can be applied at explosive and chemically hazardous facilities.
  • Research and Production Company “ERGA” produces SMBM-VP drum magnetic separators equipped with vibratory feeders, allowing reaching maximum separation efficiency thanks to uniform layer of the material fed into the separator’s working area.


    Model 2 SMBM:

    Specially for the tasks, requiring especially high purity of separated materials to magnetic and non-magnetic components (e.g. for dry separation of fine crushed magnetite ores (-25+0 mm) with maximum recovery of impurities), or with subsequent material processing by separators with different specifications in one assembly, Research and Production Company “ERGA” produces compact and efficient magnetic separators of 2 SMBM series magnetic separators with two magnetic drums.

    New magnetic separator of 2SMBM series provides a two-stage (double) separation of input material
