Abstract
Arizona Portland Cement (APC), USA, has operated a prompt gamma neutron activation analyzer (PGNAA) on its 1000 TPH overland belt conveyor system since August of 1995. The belt conveyor passes through the analyzer enclosure where a neutron source under the belt causes gamma ray releases identified by the sodium iodide scintillation detector above the belt. Sophisticated analytical software operating on a personal computer decomposes the gamma ray spectrum into its constituent elements. The result is a real-time one minute update of the complete chemical composition of the crushed rock headed down the beltline. The Crossbelt Analyzer project was a 1995 Capital Budget project. APC ordered the equipment from GammaMetrics in February and completed the installation in August 1995. Training and acceptance testing were conducted in late 1995. This paper summarizes the project after one year of operation.
