Drum separators for wet magnetic beneficiation of different ore and non-metallic materials.
Depending on magnetic separation tasks MBS separators are equipped with various types of magnetic systems (including powerful rare-earth magnet systems with magnetic induction on the drum surface to 600 mT) and bath types (for operation in concurrent, countercurrent and semi-countercurrent modes).
Uniformly distributed pulp flowing into the separator feed box is transported into the bath, where it enters magnetic field created by the magnetic system fixed inside the drum. Under the influence of the magnetic field magnetic susceptible inclusions in the pulp flow are attracted to the drum and moved by its rotating shell to the discharge area where they are unloaded into the discharge chute under the pressure of water from the nozzles along the magnetic drum.
Concurrent mode - the magnetic drum (shell) and material flow directions coincide. This prevents material building-up on the magnetic drum working surface, reduces wear and ensures lower power consumption.
Countercurrent mode - material is fed towards the magnetic drum (shell) direction. In this case magnetic particles are first attracted to the free surface of the magnetic drum at the end of the working zone by magnetic forces, then strongly magnetic particles are pressed against the surface as the working surface approaches the infeed point, thereby ensuring maximum extraction of magnetic particles.
Semi-countercurrent mode - material is underfed to the working surface (zone) of the magnetic drum. Thus, the material flow and magnetic force directions coincide, which ensures effective attraction even of very fine magnetic particles to the working area of the drum surface.
MBS magnetic separators are designed for wet beneficiation of ore and non-metallic materials with different magnetic susceptibility. These separators are used for equipping ferrous and non-ferrous beneficiation plants.

Customized process solutions can be developed to meet specific customers’ requirements.
On the basis of MBS wet drum separators “ERGA” specialists have designed special separators MBS-R for regeneration of medium solids (magnetite and ferrosilicon) used in heavy media beneficiation in processing of gold- and diamond-bearing ores, nonferrous metal and rare ores and placers.
