GEOSCAN-R
GEOSCAN-R is a high specification elemental analyser utilising Prompt Gamma Neutron Activation Analysis (PGNAA) for recycling industry applications. It is used to monitor scrap material quality in real time to assist with contaminant detection and bulk separation. It can be applied in multiple commodities such as metals, plastics, rubber, glass, etc.
The GEOSCAN-R 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 analysers use either microwave transmission technique or fast neutron and gamma transmission 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."
