The MAGQUIP SUPRSEP Rare Earth drum Separator [REDS] is high intensity magnetic separator with “Rare Earth” permanent magnets. The rotary drum separator is used for the separation, concentration or upgrading of dry granular weakly magnetic material in the size 100 microns to 50mm size range.

The magnet element is an axial alternating pole element with arc angle ranging from 180 to 210° producing up to 6000 gauss measurable on the drum surface.

The MAGQUIP Rare Earth Drum Separator is available as single pass/stage unit or alternatively in a two pass/stage version. Product configurations are magnetic, non-magnetics and middling’s retreats.

The standard range consist of 450 & 600mm diameters with drum magnet widths between 300-1500mm wide.

Material is fed from the hopper at a controlled rate onto the rotating drum shell (The feed may be presented to the top of the drum or as a ‘falling curtain’ adjacent to the drum periphery.) Magnetic particles are then deflected and held against the drum shell surface; the non-magnetic particles follow their normal trajectory. Splitters divert the particles into the outlets and chosen chute arrangement.

Various factors affect the performance of the MAGQUIP Rare Earth Drum [REDS]

Including Feed rate, drum speed & splitter position

Remove weakly magnetic particles from dry granular materials that are feebly magnetic (paramagnetic).

Typical applications and specific minerals treated are:

Concentration of: Limonite, Iron, Manganese and Nickle ores.

Removal of Pyrrhotite from nickel-copper ores.
Removal of chromite, Garnet, and Ilmenite from diamondiferous concentrates.
Removal of serpentine from magnesite.
Selective separation of Ilmenite, Garnet, Monazite.
Separation of Chrome from Silica Sand.
Recovery of ferrochrome and ferromanganese from slags.
Typical size range of material treated from 100 microns to 50 mm

The advantages of the MAGQUIP Rare Earth Drum Separator include:

  • MAGQUIP SUPRSEP magnet axial pole Rare Earth element producing maximum flux density via novel magnet pole arrangement
  • Accurately manufactured thin wall drum shell with minimal drum magnet gap, precision manufactured to close tolerance on diameter.
  • Option of high-strength fibre reinforced composite plastic; coated with two layers abrasion resistant; ‘Epoxy Gelcoat’, Two colours used for wear induction.
  • High temperature Rare Earth permanent magnet grades available for elevated material temperatures
  • Sophisticated control panel enclosure featuring PLC features for advanced component control and feedback with HMI
  • Compact modular enclosure with easy door panel access, with optional dust extraction ports
  • Direct drive to drum by shaft mount type geared motor. Reduced motor power with non-metallic shell option means ‘eddy current drag’ effect.
