GEOSCAN-S is a high specification PGNAA based system proven in many commodities to measure elements representatively in parcels as short as every 30 seconds on conveyed flow. The technology is used to digitalise conveyed flows to determine key compositional components and can be used for any conveyed bulk materials. Over 50 GEOSCAN units are installed in iron ore (measuring Fe, Si, Al, Mn, P, K, Ti, Hg and other elements as needed) with further units installed in sinter for B4 (Ca, Mg, Si, Al) basicity measurement and control. It has proven superior to other analyzers in the market in both the range of elements measured and precisions achieved over short measurement times. The GEOSCAN effectively measures contaminants such as Cu and Zn in scrap steel (typically on shredded scrap) as well as many other elements. Scantech is working with leading shredder suppliers to help supply a total quality management solution for scrap operations. Our presentation at the conference will highlight achieved measurement capabilities.
