Sorting system for the mining industry XTS

X-rayfor mineral material

Special stones such as diamonds require special designs: the STEINERT XTS The STEINERT XTS x-ray sorting system is used for dry density sorting in the lower grain size range. This sorter is based on our proven STEINERT XSS T EVO 5.0 sorting system, but offers special modifications particularly coordinated to the sorting of very valuable goods like diamonds. A transmissive procedure detects material-dependent differences in the absorption of x-rays then classifies and uses them for sorting into density classes. The extent of absorption of x-rays depends both on the material density and on the thickness or the radiated path of an object. The larger the atomic mass and the thicker a material part, the more radiation will be absorbed. The absorption in the material to be sorted is measured at two different energy levels to compensate for the influence of the object thickness. The so-called dual-energy procedure uses software to determine the material-specific absorption and thus conclude the density of the material. Radiation passing through the objects enables both a conclusion as to the medium density of an object and the identification of inclusions in rocks or clumps of material. The main advantage of x-ray transmission is that transmissive detection makes the system insensitive to surface soiling and enables the detection of inclusions. Radiation passing through the objects enables a conclusion as to the medium density of an object and thus the differentiation of stones, such as diamonds from kimberlite or alluvial sediments.
