GEOSCAN-C

GEOSCAN-C is used in cement industry applications such as stockpile building and raw mix proportioning. The world’s major cement companies are successfully optimizing their plant operations using this technology as it is proven to significantly reduce product quality variability over traditional QA procedures based on sampling.

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

The GEOSCAN-C continuously analyses the conveyed materials in real time, providing accurate results as often as every few minutes for demanding process control applications. Since the GEOSCAN-C fits on existing conveyor belts, additional sampling equipment, transfer points and material handling equipment are not required. There will be no more blending headaches. Installing a GEOSCAN analyser is the smartest way to control your operation. Blending software can further improve the results through real time reclaim and additive control (see BLENDSCAN product).

The GEOSCAN-C utilises the technique known as Prompt Gamma Neutron Activation Analysis (PGNAA). The GEOSCAN-C incorporates high efficiency detectors and state-of-the-art digital spectrometer, which overcomes the limitations of conventional, low efficiency detection systems. Enabled by enhanced electronic digitisation, PGNAA has led to a new era in process control. The optional moisture analyser uses the microwave transmission technique to measure the moisture content of the material. The key to our success is also providing an easy to use, yet sophisticated user interface, that can be easily and quickly integrated into each plant to ensure maximum return on investment.

"When commodity prices were strong and rising, mining companies could afford minor inefficiencies in their plants. That is rarely the case in these days of lower-grade deposits, lower metal prices and economic pressure from every direction. “We have to do better with lower costs,” said Philip Thwaites, manager of process control for XPS Consulting & Testwork Services. “If you’re not efficient, you’re not going to be around. And our industry can be a lot more efficient.” According to Thwaites, measurement is the cornerstone of control and efficiency. “If you have a poor measurement, or no measurement, you can’t do good control,” he explained. But this is changing. More and more mining companies are conscious of improved measurements and endorsing control, automation and next-generation technologies. What is more, there has been significant progress in automated instruments recently. These measure crucial parameters in the processing circuit and equipment to allow operators to monitor and adjust process control as needed."
