GEOSCAN

The GEOSCAN is an On- Belt Elemental analysis system for monitoring bulk materials such as limestone and iron ore.

It can be used on a very wide variety of applications, with automatic bed depth correction included as a standard feature.

The GEOSCAN continuously analyses conveyed materials in real time, providing accurate results as often as every one minute for demanding process control applications. Since the GEOSCAN fits on existing conveyor belts, additional sampling equipment, transfer points and material handling equipment are not required.

The GEOSCAN utilises the technique known as Prompt Gamma Neutron Activation Analysis (PGNAA). The GEOSCAN incorporates high efficiency detectors and state-of-the-art digital spectrometer, which overcomes the limitations of conventional, low efficiency detection systems.  The optional moisture analyser uses the microwave transmission technique to measure the moisture content of the material.

""The economic benefit gained from use of the Coalscan on-line ash monitors in most cases results from control of mining and plant operations closer to the required specification ash content. A number of independent studies have estimated the benefits of on-line ash analysis to average more than A$500 000 per year per installed gauge.""
