LS-20-09 X-Ray Sorter

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, - 10 + 5 mm

Material feed and transportation system

Continuous flow system, single-pass. Loading hopper (with a flange to connect to the mill's transportation system) - gravity feeder with automatically controlled slide valve - a shaping slope chute (300 mm wide) - adjustable outer divider plate (concentrate-tailing) - concentrate and tailing channels (with flanges to connect the relevant pipelines of the mill).
Non-single layer feed of material to the analysis area is allowed.

Throuput rates

100 t/hr (- 50 + 20 mm)
60 t/hr (- 20 + 10 mm)
30 t/hr (- 10 + 5 mm)

X-ray:

number of tubes
mode of radiation

anode voltage, anode current

Two-sided eliminate of material flow in the freefall chute.
2
Pulse type (pulse length - 0.5 ms; pulse period - 4 ms).
35 kV max.; 350 mA

Detection:

Luminescent signals' receivers
number of receivers, number of detection channels

Two-sided material luminescent detection.
Photomultipliers (PHM);
8 (4 on each side of the material flow). Each receiver is provided with an optical system to localize the detection area; so, the material flow is divided across the width to four detection areas.
Analogue-to-digital detection system; options include operation both in amplitude-time mode and in special mode, increased selectivity, using kinetic features for luminescent.

Ejection

Pneumatic, with compressed air, by means of solenoid-operated pneumatic valves
5-channel splitter The valves are actuated after their combination algorithm, depending on detection area, where the object was detected.

Recovery

99% minimum

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

1.1 kg maximum (- 50 + 20 mm), 0.65 kg (- 20 + 10 mm), 0.35 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.

Electric power supply
