Abstract: The quality of cement raw meal ingredients directly affects the quality, output and energy consumption of clinker, at present, most of the raw material proportioning control of domestic cement production lines adopts the quality control system based on laboratory X-ray fluorescence analyzer, and this paper analyzes the analysis lag, poor sample representativeness, human factor error and other problems of this quality control system. The neutron activation online analyzer adopts instantaneous γ neutron activation analysis technology, which can identify the types and contents of material elements by detecting the energy and intensity of characteristic γ rays, so as to realize online real-time quality control of cement raw meal batching, and can perform 60 raw meal proportioning analysis calculations and adjustments per hour. After the application of neutron activation on-line analyzer to cement production, the static calibration and dynamic operation calibration results show that the neutron activation online analyzer has stable performance, high detection accuracy, and improved the qualification rate and stability of raw meal and clinker rate values.
