Material to be processed

Dry, thoroughly dedusted, classified (contents of main class 85% minimum)

Material grain size classes

- 6 + 3 and -3 + 1mm.

Material feed and transportation system

Flow type. 4- stream type. Two treatment pass. Loading hopper (with a flange to connect to the mill's transportation system) - shaking feeder for Pass 1 - shaping slope chute for Pass 1 - shaking feeder for Pass 2- shaping slope chute for Pass 2 - adjustable outer divider plates for Pass 1 and 2 (concentrate-tailing) - concentrate and tailing channels (with flanges to connect to the relevant pipelines of the mill).
Slope chutes and shaker feeder chutes are divided into 4 streams (one stream 24 mm wide)

Only single layer feed of material to the analysis area is allowed.

Throuput rates

300 kg/hr (- 3 + 1 mm);
600 kg/hr (- 6 + 3 mm)

X-ray:
number of tubes
mode of radiation

anode voltage, anode current

2 (one tube per each pass).
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 per each pass Channel-by-channel edjection

Recovery

99% minimum

Outward flow of material per one splitter (with Throuput rate)

Max. 2.0 g (- 6 + 3 mm), 1.0 g (- 3 + 1 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 checking from the concentration mill's Automated Process Control System

Only if special smart cards are available and by commissioning.

Electric power supply

 380V ± 10%; 50 Hz±2%; 4 kVA

Flow rate for potable quality water to cool the tubes

6 l/min max.
