Material to be processed

Wet, clean from mud and sorted materials, classified (contents of main class 85% minimum)

Material grain size classes

- 50 + 20; -20 +10 and -10 + 5 mm.

Material feed and transportation system

Flow-type, two treatment pass.
Loading hopper (with a flange to connect to the mill's transportation system) -gravity feeder with an automatically controlled slide valve- a shaking feeder -a shaping slope chute for Pass 1 and 2 (300 mm wide) - adjustable outer divider plates for Pass 1 and 2 (concentrate-tailing) - concentrate (per each pass) and tailing channels (with flanges to connect the relevant pipelines of the mill).
Only single layer feed of material to the analysis area is allowed.

Capacity

To 30 t/hr (- 50 + 20 mm)
20 t/hr (- 20 + 10 mm)

X-ray:

number of tubes
mode of radiation

anode voltage, anode current

One tube per each pass.
2
Pulse type (pulse length - 0.5 ms; pulse period - 4 ms).
35 kV max.; 350 mA

Detection:

Luminescent signals' receivers
number of receivers, detection channels

Single-sided material luminescent detection.
Photomultipliers (PHM);
8 (4 per each pass).
Analogue-to-digital detection system; options include operation both in amplitude-time mode and in special mode, increased selectivity, using kinetic features for luminescent (extra selection effect is ensured by luminescent-absorption analysis mode).

Ejection

Pneumatic, with compressed air, by means of solenoid-operated pneumatic valves
4-channel splitter (1 valve per each channel) at each pass Channel-by-channel edjection

Recovery

98% minimum

Outward flow of material per one splitter (with maximum capacity)

0.2 kg maximum (- 50 + 20 mm), 0.15 kg (- 20 + 10 mm), 0.05 kg (- 10 + 5 mm)

Automation

Extra option (supplied after a special order): Protection system against unauthorized access to SM, material

Checking of main systems prior to start of material feed and in the course of operation (material feed is stopped if fault is detected) Sensitivity Failure indication. Monitoring and control from the concentration mill's Automated Process Checking System

Only if special smart cards are available and by commissioning.
