Redwave to showcase redesigned XRF sorting machine at IFAT

Initially used in the field of glass sorting, a new machine design allows the Redwave XRF to sort nonferrous metals.

Austria-based Redwave says it will showcase its updated X-ray fluorescence (XRF) sorting machine at the IFAT 2016 exposition in Munich, 30 May to 3 June.

At Redwave’s booth, located in hall C1 at stand 226 at IFAT, the company says it will display different live sorting demonstrations with the Redwave XRF sorting system at its stand, including:

  • mixed heavy metals: separation of pure fractions (eg., copper, zinc and stainless steel);
  • mixed plastics: separation of brominated plastics; and
  • mixed glass: separation of lead glass and heat resistant glass.
The supplier says the Redwave XRF sorting system was initially used in the field of glass sorting, specifically for the separation of heat-resistant and leaded glass from the waste glass cullet. However, the company says soon it became apparent that the fields of application go far beyond the glass sector. The use of this innovative technology together with the development of a new machine design set new standards in the metal sorting, in particular the sorting of nonferrous metals. Using this technology, Redwave says it is possible to separate material, which until now was considered not sortable.

Beyond the high throughput and purity, Redwave says the flexible and versatile application possibility of the XRF sorting technology is an advantage compared with sorting techniques such as camera or X-ray transmission. The applicability of the XRF technology is multifaceted and not limited to one material class or application. Compared with other technologies, moisture, coloring and surface contamination have no significant negative impact on the detection, Redwave explains.

High-purity metal fractions are produced due to the sorting processes, which can be sold directly and profitably, the company says. The flexibility of the XRF technique and the sophisticated sorting logic make it possible to respond to changes of the sorting processes as quick as possible. Furthermore, a variety of sorting steps can be carried out with the same machine and different preset sorting programs.
