Longi-Multotec Heavy Media Drum Separators

The Longi-Multotec heavy media drum separator (HMDS) improves grade and recovery in dense medium recovery processes. Through combining internationally-leading magnet technology, an established, application- and context-specific experience in mineral processing and trusted, high-quality configurations, materials and parts, Multotec improves the performance of dense media mineral recovery operations.

As the pioneers of the use of rare-earth magnets in wet low intensity magnetic drum separators, the Longi-Multotec HMDS utilise Neodymium Ferrite Boron (NeFeB) magnets to increase magnetic induction values from the conventional 2 000 nominal Gauss to 2 500 or 3 000 Gauss, allowing a stronger attraction of dense media for a more efficient recovery process.

The HMDS is supplied in standard drum sizes of a 900mm or 1 200 mm diameter, with widths from 1.2 m to 3 m. Larger machines can be custom designed and manufactured on request. The drum shells are 4 mm thick with 3 mm wear wraps, and are constructed from SUS 304 Stainless Steel. Rubber or ceramic wear linings can be installed, should your application require it.

Our Longi-Multotec heavy media drum separator features:

  • Magnetic induction up to 3 000 Gauss
  • Specially-engineered magnetic circuits facilitate the optimum use of rare-earth magnets
  • Axial pole configuration for improved recovered material grade
  • Optional polytetrafluoroethylene-lined butterfly valves in discharge pipes provide accurate level control
