X-ray transmission sorter RGS-1М
X-ray sorter RGS-1М is designed to enrich diamond material with grain size – 6 + 3mm in the diamond industry.
Principle of sorter operation is based on the difference in X-ray absorption by material with various atomic density.
The primary advantage of RGS-1М over modern X-ray luminescent sorters is the possibility to identify and recover diamonds from the material flow irrespective of their X-ray luminescence features (poor luminescent or not fluminescent).
The sorter includes a sorting machine (SM) and an automated control rack (ACR).
