The POLUS-M sorter is designated for the re-treatment of diamondiferous concentrate with grain size - 5 + 2, - 2 + 1, and -1 + 0.5 mm,
afield, with the objective to carry out geological exploration of diamond deposits.
The sorter's operation concept is based on the use of diamonds' property of luminescent under X-ray impact and on the difference of those properties with diamonds and associate luminescent minerals. This is the implementation of the mode conditionally labeled as "luminescent and absorption", when the X-ray tube and luminescent receptors are located on both sides of the material flow. Herein, the effect of difference in X-ray absorption by diamonds and associate luminescent minerals is used.
The sorter includes a sorting machine (SM) and a control and detection unit (CDU).
