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.
"Most power plants are ‘flying blind’ and don’t know the quality of their coal, the #1 raw material cost consumable. Every power plant needs on line analysis of coal and bunker modeling to predict boiler efficiency and prevent deratings from boiler slagging."
