X-Ray Sorting System XSS®
One important application of X-Ray Sorting System is the separation of mixed light and heavy metals after the iron content has been removed by magnetic separators, such as the mixed non-ferrous product from eddy current separators. The XSS® makes it possible to separate aluminium and magnesium from the heavy metals fraction such as copper, bronze, zinc and lead. It is also possible to separate cast aluminium from wrought aluminium-based alloys.
When processing minerals, metal bearing rock can be separated from metal-poor rock or coal from field stone. This saves large amounts of energy in the area of fine milling and fine-grain sorting, thus substantially improving the economics of current mineral processing operations. Composite material systems and even surface details in organic materials can also be recognized and separated by the X-ray Sorting System. Even plastics and wood can be separated.
The detecting principle reacts to the atom mass of each chemical element. The technology at the heart of the X-ray Sorting System XSS® is based on the transmission of X-rays, i.e. X-rays are transmitted through the material to be sorted and an X-ray sensitive camera determines the intensity of the radiation. A computer determines the difference between the incidental and the transmitted radiation. The resulting intensity difference - the absorption - can be used to draw conclusions about the atomic composition of the scanned material. The system creates a near reality image sufficient to enable subtle evaluations to be carried out.
