摘要

自1995年8月以来，美国亚利桑那波特兰水泥公司(APC)在其1000 TPH陆上带式输送机系统上运行了一台快速伽马中子活化分析仪(PGNAA)。带式输送机通过分析器外壳，其中带下的中子源引起伽马射线释放，由带上方的碘化钠闪烁探测器识别。在个人电脑上操作的复杂分析软件将伽马射线光谱分解为其组成元素。其结果是一分钟内实时更新了沿腰带而下的碎石的完整化学成分。交叉带分析仪项目是1995年的资本预算项目。APC于2月向GammaMetrics订购了设备，并于1995年8月完成了安装。1995年后期进行了培训和验收测试。本文对该项目运行一年后的情况进行了总结。

Performance evaluation of an on-line PGNAA cross-belt analyzer [cement plant monitoring]

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.
