Industry
Mining industry
Mining operations run in heavy dust, vibration and constantly changing material volumes. RETTAR radar and laser scanners deliver accurate level, volume and flow data where ordinary sensors lose accuracy or fail outright.
Typical applications and solutions
Haul truck loading station control
Precisely measuring the truck bed profile and the falling material profile lets the control system calculate the loaded volume in real time, improving loading efficiency and reducing material loss.
Measurement challenges
Heavy dust and moisture, possible corrosive gases; material height and volume change continuously, requiring accurate real-time tracking of the dynamics.
Solution
Radar level meter + laser profiler + laser radar
Ore bin level control
Ore is conveyed into surface or underground bins for intermediate storage. Continuous level measurement and limit-level control keep bin operation safe and efficient.
Measurement challenges
Uneven ore particle size, significant reflectivity variation, dust interference.
Solution
Radar level meter + microwave point level switch
Belt conveyor flow monitoring
Real-time control of the material flow on the belt lets operators adjust belt speed or feeder mode in time to keep the process stable.
Measurement challenges
Changing material properties make measurements unstable and the material layer uneven, complicating dynamic monitoring.
Solution
Laser profiler
Crusher bin level measurement
The crusher's receiving bin takes run-of-mine ore delivered by haul trucks. Level control here is important but difficult given the operating environment.
Measurement challenges
High material throughput, heavy dust generation, high humidity.
Solution
Radar level meter + radar 3D scanner
3D ore stockpile monitoring
A 3D stockpile model provides accurate volume and distribution data for inventory management and planning, and is also used in stacker/reclaimer anti-collision systems.
Measurement challenges
Irregular stockpile shape due to uneven terrain and material surface.
Solution
Laser scanner + radar level meter + radar 2D scanner
Tailings level/density control
Continuous measurement of tailings slurry concentration and flow during transport to the tailings storage facility ensures process stability and safety.
Measurement challenges
Complex slurry composition, poor flowability, significant temperature and pressure fluctuations.
Solution
Radar level meter + slurry density meter / electromagnetic or acoustic flowmeter
