The GammaScan™ and GammaScanDUO™
Bring together world-best innovation and smartest technology
delivering the most advanced coal ash analyser, and combined coal ash and moisture analysers, in the world today.
Measurement, without the delay
Measuement in mining and understanding the material’s composition is vital at every stage, allowing operators to maximise product value, maximise efficiency and minimise risk. With value dependent on material content, small changes can drastically alter the end value of the material. Without measurement, operators are incapable of determining material value and run the risk of drastically reducing revenue.
Remote support at your fingertips
Dedicated workflows to help your team analyse technical issues means you can keep your sensors running optimally. For more difficult requests, our team is available 24/7 to assist you.
Working Principle
The GammaScanDuo analyser is an on-line “natural gamma and low level microwave” CV
(calorific value) measurement system which is easily installed on conveyor belts. The system does not contain any nucleonic sources and therefore does not require a radiation licence for its use.
The GammaScanDuoTM measures moisture and the low levels of naturally occurring gamma radiation in the coal being transported on a conveyor. This radiation mainly arises from elements like U, K, and Th which are naturally present in coal. The amount of these elements present has been shown to correlate well with the amount of the main ash forming elements (Si, Fe, Al, Ca) and so the gamma count rate correlates to ash content.
By combining the ash measurement with moisture, tonnage and the DAFV (dry ash free value) of the coal CV can accurately be determined.
