Rare Earth Drum Separators (REDS)

MAGQUIP SUPRSEP Rare Earth Drum Separator (REDS)

High-Intensity Rare Earth Drum Separator for Dry Mineral Concentration

The MAGQUIP SUPRSEP Rare Earth Drum Separator (REDS) is a high-efficiency permanent magnetic drum separator designed for the dry separation, concentration, and upgrading of weakly magnetic materials. Fitted with powerful rare earth neodymium magnets, the SUPRSEP drum generates high-intensity magnetic fields ideal for fine to coarse particle sizes ranging from 100 microns to 50 mm.

Powerful Magnetic Performance

At the heart of this separator is an axial alternating pole magnetic element with an arc coverage between 180° and 210°, delivering surface field strengths of up to 6000 gauss. This configuration ensures effective magnetic capture and retention across a wide range of materials, including heavy mineral sands, rare earth ores, industrial minerals, and metallic fines from recycling streams.

Flexible Multi-Pass Design

The MAGQUIP REDS unit is available in single-pass or two-stage configurations, allowing for enhanced separation efficiency through middlings retreat or multiple product splits. Output streams typically include:

Magnetics
Non-magnetics
Middlings (optional retreat)

Engineered for Operational Flexibility

Standard drum diameters include 450 mm and 600 mm, with magnet widths from 300 mm up to 1500 mm. Custom widths and feed assemblies can be configured to suit plant layout and capacity requirements, ensuring seamless integration into your dry processing circuit.

Key Features:

Rare earth permanent magnet system for sustained high-intensity fields
Dry operation – no water or slurry handling required
High recovery and product grade in a compact footprint
Low maintenance design with robust construction for industrial environments
Suitable for mineral sands, rare earth elements, non-ferrous recycling, and more

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
