| Material to be processed || Wet, clean from clay and slurries, classified (fineness from separated class is 5 % max., crushing from separated class is 10% max.)|
| Material grain size fraction || – 50 + 20, – 20 + 10, – 10 + 5 mm |
| Material supply and transportation system || Continuous flow system, single-stage with gravity feeder.
Non-single layer supply of material to the analysis area is allowed.

60 t/h (– 20 + 10 mm)
30 t/h (– 10 + 5 mm)
| X-ray: |
| number of X-ray tubes || 2
Two-sided exposure on material flow in the freefall tray.
| mode of radiation || Pulse type (pulse duration - 0.5 ms; pulse period - 4 ms |
| anode voltage, anode current || (33-2) kV max.; (330±10) mA |
| Detection |
| Two-sided material luminescence detection.
Each receiver is provided with an optic system to localize the detection area; so, the material flow is divided across the width into four detection areas.
Analogue-to-Digital Processing System; operation both in amplitude-time mode and in special mode (increased selectivity, using kinetic features of luminescence) is possible.
| luminescent signals' receivers || Photomultipliers (PHM) |
| number of detectors, detection channels || 8 (4 on each side of the material flow). |
| Ejection || Pneumatic, with compressed air, by means of solenoid-operated pneumatic valves.
5-channel stopping mechanism. The valves are actuated according to the certain algorithm depending on detection area, where the object was detected.

0.65 kg (– 20 + 10 mm)
0.4 kg (– 10 + 5 mm)
| Automation || Checking of main systems prior to start of material supply and in the course of operation (material supply is stopped if fault is detected). Sensitivity control. Failure indication. Monitoring and control from the APCS of enrichment plant.
Protection system against unauthorized access to SM, material only if special smart cards are available.
| Electric power supply || 1 phase; (220±22) V; (50±1) Hz |
