| Abstract: | The paper introduces an on-line automatic monitoring system. This system can continuously and automatically monitor the concentrating iron ore on conveyer belt by means of radioisotope X-ray fluorescence analysis and overcome the shortcoming that the traditional samplingchemical analysis causes serious time delay. It plays an important role in directing production process and improving the quality of products. This system consists of radioisotope source, scintillation detector,amplifier circuits , pulse amplitude analyzer, spectrum regulator, signal transfer channel,interface unit,large LED display screen and a set of microcomputers. It has obtained a verysatisfactory result since mounted on a V-Ti-magnetite production line in Panzhihua Ore DressingPlant. The absolute error is equal to or less than 0. 5%,and the ratio up to standard is 90. 81%. |
