Abstract

The invention discloses a technology for increasing a limestone CaO (calcium oxide) contrast qualified rate through fluorescence analysis. The technology comprises the following steps: (a) ensuring that no objects are placed within the range of 10 cm around scales; (b) adjusting the drifting quantity of a spectrum; (c) ensuring that the stirring is uniform, wherein the adjusted limestone comprises the following components in parts by weight: 52.04 parts of CaO, 12.6 parts of SiO2, 2.30 parts of Al2O3, and 1.22 parts of MgO. According to the technology for increasing the limestone CaO contrast qualified rate through the fluorescence analysis, the defects of large weighing error, large spectrum drift, non-uniform stirring and the like in the prior art can be overcome, and the advantages of small weighing error, small spectrum drift and uniform stirring are achieved.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a process for improving the pass rate of limestone CaO comparison in fluorescence analysis. Background technique [0002] X-ray fluorescence analysis is a method for quickly determining the chemical components of various materials. This method has been widely used in the cement industry because of its fast and accurate characteristics. At present, our company adopts this method in the analysis of limestone, sand shale, raw meal, clinker, cement and other samples. Limestone is one of the important raw materials for our company's cement production. It is the source of calcium raw materials in cement. The content of CaO in limestone directly affects the saturation ratio of cement clinker, which in turn affects the strength of clinker, and finally affects the strength of cement. If the CaO content in limestone is too low, the clinker saturation ratio will be low, the cemen...
