Portable sorter POLUS-M
Technical data
| Material to be processed | Dry, dust-free, classified (contents of main class 85% minimum) |
| Material grain size fraction | -8+5, -5+2, -2+1, -1+0.5 mm |
| Material supply and transportation system | Flow type, 1-stream, 1-stage with vibrofeeder.
Only single layer feed of material to the analysis area is allowed, filling index of the tray is from 5 to 80%. |
| Throughput (rated) |
100 kg/h (-8+5)
50 kg/h (-5+2)
30 kg/h (-2+1)
15 kg/h (-1+0.5) |
| X-ray: |
|---|
| number of X-ray tubes | 1 |
| mode of radiation | Pulse type (pulse duration – 400+20-40 µs; pulse period – 2.6±0.2 ms). |
| anode voltage, anode current | 30 kV max.; 10 mA |
| Detection: |
|---|
Single-sided material luminescence detection.
Analogue-to-digital detection system; operation both in amplitude-time mode and in special mode - increased selectivity using kinetic features of luminescence (extra selection effect is ensured by fluorescent-absorption analysis mode). |
| luminescent signals' receivers |
photomultiplier tubes (PMT)
|
| number of detectors, detection channels | 1 |
| Ejection | Mechanical type. Metal blade with solenoid drive |
| Recovery rate | 98% minimum |
| Yield per ejection (with maximum capacity) |
2.2 g (-8+5)
1.7 g (-5+2)
1 g (-2+1)
0.5 g (-1+0.5)
|
| 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. |
| Electric power supply | 1 phase; (220±22) V; (50±1) Hz |
| Power consumption | 300 VA max. |
| Cooling of the X-ray tube | Air cooling |
| Overall dimensions (L×W×H), weigth: (stowage boxes not included) |
|---|
| SM | 635×300×590 mm, 36.5 kg (incl. SPTA and installation kit); |
| CRU | 490×440×290 mm, 15 kg |
| Operation Conditions: |
|---|
| Ambient air temperature | from + 5°С to + 45°С |
| Relative humidity (at ambient air temperature + 25°С) | 80% max. |
| Protection against X-rays | Specially designed construction of the sorter totally protects against the X-ray. Each unit is being tested for safety. |
