Portable sorter POLUS-M

Sorter POLUS-M is designed to treatment dry diamond concentrate with grain size – 8 + 6, – 6 + 3 and – 3 + 1 mm in the field in order to carry out geological exploration of diamond deposits.

The sorter operation concept is based on the use of diamonds’ property of luminescence under X-ray impact and on the difference of those properties with diamonds and associate luminescent minerals. The mode under reference term “luminiscence and absorption” when the X-ray tube and photo detectors are located on both sides of the material flow is implemented. The effect of difference in X-ray absorption by diamonds and associate luminescent minerals is used.

The sorter includes a sorting machine (SM) and control and registration unit (CRU).
