Dense Medium Cyclones

Proven to improve efficiency across the world’s toughest iron ore, platinum, diamonds and coal preparation applications, Multotec manufactures a complete range of dense medium cyclones for your application.

With high chrome alloys and a specially engineered alumina wear tile, together with our Scrolled Evolute design, Multotec DMS cyclones deliver improved wear resistance, reduced maintenance, and a greater product lifespan to help you optimise your cost-per-ton targets.

Our Dense Medium Cyclones are engineered for:

  • Maximum separation efficiency
  • Reduced misplacement of product 
  • Minimised turbulence
  • Reduced wear, especially on the vortex finder
  • Lower energy consumption

We have distributors and branches in 69 countries on every continent, ensuring rapid lead times, large stockholdings of spares and tailored engineering and field services to help you process mineral more efficiently and productively.

Multotec dense medium cyclones are field tested to improve separation accuracy and efficiency.

Design innovations, increasing performance

The Scrolled Evolute head design

The Scrolled Evolute design is the heart of Multotec’s dense medium cyclone efficiency! Together with the specialised engineered tile wear surface, the Scrolled Evolute design ensures maximum separation efficiency and wear life from your hydrocyclone.

Through extensive testing and simulations, has Multotec proven that the Scrolled Evolute inlet design has a higher capacity when compared to standard inlet configurations. This design substantially reduces vortex finder wear, thereby reducing operating costs while maximising cyclone efficiency. The result is also a stable air core inside the cyclone and reduced energy consumption in heavy medium separation.

The Scrolled Evolute design helps operators achieve high separation efficiencies at lower operating pressures, reducing overall energy consumption in the process and improving capacity.

The engineered tile wear surface

Each engineered tile is specifically designed for its position in the complete tile kit, ensuring a very tight fit, with the absolute minimum space at the end of the tile joints. The widths are selected to provide a smooth internal surface, resulting in a long-lasting wear surface.

Engineered tiles are pressed with chamfered sides and then, while in the green state, are cut precisely to the required shape. This ensures that gaps between the tiles are minimised.

Standard pressed tiles are hand cut, which results in gaps between the tiles. Because the epoxies used to bond the tiles wear more rapidly than alumina tiles, the tile surface becomes increasingly uneven during operation, resulting in accelerated wear.

The science behind the cyclone

As a global leader in cyclone separation efficiency, Multotec understands the common process factors that affect your cyclone performance. Our cyclone product specialist, Ersnt Bekker, highlights all the performance parameters Multotec measures when selecting the ideal dense medium cyclone, or other dense media separation equipment, for your application.
