Coal industry
The coal industry combines mining and logistics tasks: loading onto transport, long-term stockpiling, and beneficiation. RETTAR radar and laser technology provides accurate volume accounting and conveyor control in heavily dusty conditions.
Typical applications and solutions
Coal loading control into rail cars and trucks
Calculating the loaded coal volume from the vehicle bed profile provides accurate dispatch accounting and reduces losses from over- or under-loading.
Measurement challenges
Dust, vibration, variation in coal moisture and density.
Solution
Radar level meter + laser profiler
3D coal stockpile monitoring at the yard
Volume control and timely stockpile rotation reduce the risk of spontaneous combustion and provide accurate inventory data.
Measurement challenges
Dust, changing stockpile shape, large yard area.
Solution
3DPro2300 radar 3D scanner / laser scanner
Coal level control in preparation plant bins
Controlling intermediate coal storage ahead of beneficiation ensures a steady feed to the processing line.
Measurement challenges
Uneven particle size, build-up of wet coal.
Solution
Radar level meter + microwave point level switch
Belt conveyor monitoring at open-pit coal mines
Controlling material flow and belt centering along long conveyor runs reduces the risk of emergency shutdowns.
Measurement challenges
Long conveyor runs, temperature swings, belt wear.
Solution
Laser profiler + belt centering system
