Comparison of in-line ore analyzers
Flow ore analyzers have become widespread throughout the world among enterprises in the field of mining and processing of mineral raw materials. Their use makes it possible to obtain data on the composition of raw materials in real time directly on conveyors, without sampling, which makes it possible to quickly manage the technological process.
Based on the type of excitation source of the substance under study, all flow analyzers can be divided into 4 types:
- devices with an X-ray tube;
- radioisotope;
- laser;
- neutron.
The radioisotope analyzer is the ARP-1Ts device , manufactured by Tekhnoanalitpribor LLC, Moscow.
Below is a comparative table of characteristics of flow analyzers depending on the type of excitation source.
| Options | Devices with X-ray tube | Radioisotope | Laser | Neutron | Optical |
|---|---|---|---|---|---|
| Analyzed elements | A1 to U | Mg to U | from C to U | from C to U | from H to Mt |
| Ambient temperature range, oC | -20 to -45 | -30 to +50 | -20 to -45 | -30 to +50 | |
| Dimensions, mm | S90x275x240 | Sensor 150x140x300 Power cabinet 300x250x170 | 1500x800x1300 | 2103x1690x1575 | Lighting unit 2000x2000x1000 Cabinet with electronics 1300xS00x200 |
| Weight, kg | 45 | Sensor 5 Power cabinet 6.5 | 450 | from 2721 to 4081 | ISO |
| Analysis of pulplike materials | — | + | — | — | — |
| Area/volume of analysis | Surface | Volume | Surface | Volume | Surface |
| Detection limits and accuracy | For all in-line analyzers — up to lOOppm (0.01%), varies depending on elements | ||||
| Hazard to personnel health | There is | unlikely | No | There is | No |
| Analysis frequency, samples/min | continuously | continuously | 3-20 | 1, possibly continuously | 20 |
The choice of the type of excitation source is individual and depends on the problem that needs to be solved at a particular enterprise.
