STEINERT WDS – the large wet drum magnetic separator

Highly efficient recovery of ferrosilicon or magnetite from sink/float separation and wet processing of fine grains

The STEINERT WDS is frequently used especially in the processing of heavy solutions or iron ore at grain sizes between 1 µm and 3 mm. Our wet drum magnetic separator basically ensures the recovery of magnetite or ferrosilicon (FeSi) in the regeneration of heavy solutions. The use of powerful magnets made from neodymium-iron-boron and the special design of the magnet packages achieve high field strengths enabling high separation rates of over 99%.

We offer the magnetic drum separator with different magnetic field strengths: as the strong field WHIMS, medium field MIMS weak field LIMS separator. The large STEINERT WDS wet drum magnetic separator therefore works extremely efficiently. A second separation stage can thus frequently be excluded due to the high separation rates.

The magnetic system here is positioned eccentrically. This means that the magnetic force is only at its maximum in the sorting zone. Removal from the drum occurs very reliably in an area that has no magnetic fields. Two different versions of the STEINERT WDS matched to your specific application are at your disposal; these operate with different directions of drum rotation. The drum can either rotate in the advancing solution's flow direction or against the flow, the so-called "climax style". Optimisation is achieved by the different operating modes depending on the proportion of magnetic particles, target grain size and desired throughput.

The current design of our separation container increases the ease of maintenance and also ensures reliable operation. Easy to clean filter meshes in the feeder also prevent the entry of parts that are too large. Homogeneous feed and discharge over the entire drum width also ensure a laminar flow, thereby optimising the conditions for separation.

Diameters up to 1.2 m and working widths up to 3.6 m are just as possible as cascade or parallel arrangements at higher throughput rates. There is also a version available as a double magnet separator, for example, which provides additional benefits like space saving or a reduced need for peripheral equipment.

  • WDS = wet drum separator
  • Various versions and operating modes are possible
  • Throughput: < 150 m³/h per metre of working width (depending on the respective deployment conditions)
  • Working widths up to 3,500 mm with diameters of 915 mm or 1,200 mm
