摘要
利用一款基于瞬发γ中子活化原理设计的主要针对皮带散状物料元素进行在线检测的工业仪器,研究这款仪器用于测量铝土矿组成分析的可行性,实验主要进行了两组样品中Ca、Si、Al、Fe、Ti五种元素的测试,其中一组样品由高纯氧化物组成,一组样品由铝土矿和高纯氧化物组成,测量结果表明,CaO、SiO2、Al2O3、Fe2O3、TiO2的测量精度分别为±0.23%、±0.18%、±0.35%、±0.14%、±0.08%,能够满足原料自动配比及入厂原料质量控制的要求。
An industrial prompt-gamma neutron activation analysis（PGNAA） system, designed for the real-time elemental analysis of bulk materiel on a conveyor belt,has been studied to examine the feasibility of using such a system for bauxite composition analysis. Experiments were conducted to measure Ca Si Fe A1 in two simple,one simple is comprised of pure oxide, and the other simple is comprised of bauxite and pure oxide. The static accuracy are ± 0. 23% （CaO）, ± 0. 18% （SiO2）, ± 0. 35%（Al2 O3 ）, ± 0. 14% （Fe2 03 ）, ± 0.08 % （TiO2）. The instrument can meet the requirements of automatic mixing system of row material and quality controlling after entering factory.
