Using in-depth experience of work with ore and mining enterprises, research and production company «Erga» designed and tested magnetic drum separators (SMBM-2 VP model) for effective concentration of medium-magnetic and weakly-magnetic  ore. New separator model utilizes the power of rare-earth permanent magnets - magnetic induction of the surface of the drum reaches 900 mTsl (9000 oersted), gradB = 8.81 Tsl/m, tractive force = 4.78 q (q = 9.81 m/sec²).

Application

SMBM-2 VP magnetic drum separators are designed for concentration of medium- and weakly-magnetic ore and nonmetallic materials (for obtaining high quality concentrates and protecting technological equipment from breakages, caused by tramp iron).

Principle of operation

SMBM-2 VP magnetic separators are used for extraction of ferromagnetic particles from various products. Magnetic system (180° sector) is installed on a magnetic drum which is fixed inside a  replaceable stainless steel shell, rotated around the magnetiic system by the motor-reductor. Separation product is fed through the loading hopper directly on the rotating shell. Ferromagnetic particles are drawn to the surface of the shell under the influence of a powerful magnetic field, and stay there until the rotating shell goes beyond the magnetic sector of the drum. The magnetic field disappears and ferromagnetic particles are discharged from the shell, while non-magnetic components of the product continue moving on their original trajectory.

A multipolar magnetic system guarantees efficient extraction  of occasional magnetic particles from  product aggregates, minimizing product losses and improving its quality.

Magnetic drum separators are supplied with control boards with  frequency converters. Self-cleaning design guarantees non-stop automatic discharge of ferrous metals from the drum surface and eliminates influence of the "human factor" on the separation process.

SMBM-2 VP magnetic separators are equipped with vibratory feeders for even product distribution on the surface of the magnetic drum. Several types of adjustment systems  (slide gate, splitter, variable frequency electric drive, etc.)  provide complete control over the separation process.

Summary

Main advantages of the SMBM-2 VP model are: high efficiency, low energy consumption and high economic profitability. SMBM-2 VP magnetic separators are suitable for various industries – mining and smelting, glass, wood processing, recycling, etc.
