X-ray transmission sorter RGS-2

X-ray sorter RGS-2 is designed to enrich diamond material with grain size – 6 + 3mm in the diamond industry. It can operate as a pre-final treatment sorter at reduced throughput.

Principle of sorter operation is based on measurement of X-ray material absorption at two different X-ray radiation energies (dual X-ray energy absorptiometry). It allows separation of materials with different atomic (charge) number (or element number in Mendeleev Periodic Table), i.e. diamonds (Z=6) and rock (Zeff=12).

The primary advantage of RGS-2 over modern X-ray luminescent sorters is the possibility to identify and recover any diamonds from the material flow irrespective of their X-ray luminescence features (poor luminescent or not luminescent).

The sorter includes a sorting section (SS) and electronic section (ES) connected together.
