Abstract

The invention discloses a process capable of improving the contrast qualified rate of CaO in limestone by fluorescence analysis. The process comprises the following steps: a, ensuring that no object in a range of 10cm around a scale; b, adjusting spectrum drift amount; and c, ensuring uniform mixing, wherein the adjusted limestone comprises the following components in parts by weight: 52.08 parts of CaO, 12.9 parts of SiO2, 2.28 parts of Al2O3 and 1.2 parts of MgO. By virtue of the contrast qualified rate of CaO in limestone by the fluorescence analysis, the defects of great weighing error, great spectrum drift and non-uniform stirring in the prior art can be overcome; the advantages of small weighing error, small spectrum drift and uniform stirring are implemented.

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 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 cement strength ...
