Technical design features:

The feeder has easy-change screening surfaces.
The rotation of the cone slicer, in contrast to existing designs, is carried out using a worm gear motor rather than a belt, which dramatically increases the reliability of the separator as a whole and reduces its cost.
The system of gamma-ray detection blocks has an increased sensitivity for measuring the specific activity of each piece, which allows us to expand the range of sizes of pieces.
Measurement of the weight of a piece is carried out by the gamma-field effect method programmatically without the use of size sensors.
The position of the piece in front of the separating device is fixed using a special detection unit with a collimator.
In the detection units, sensitivity is automatically adjusted according to the light or gamma-raper using precision spectrometric electronics.
All mechanics and electronics are designed for underground use.

The design of the separator is easily disassembled, which creates the necessary conditions for the movement of the separator in underground conditions.
