Description
Summary:According to the radioactive characteristics of thorium ore and for the industrial production needs of thorium deposits in Baiyune, an online detection system for thorium ore concentrator with ten pulse counting was developed to realize real-time detection and ore beneficiation. The influence of the belt speed, ore shape, belt thickness, distance from the detector to the belt and other factors in the detection system on the γ energy exposure rate (intensity) in the incident NaI(Tl) crystal and the crystal detection efficiency are derived theoretically. Finally, it is made about the error evaluation of the online system in industrial production.
