Abstract

The invention discloses a process capable of increasing the CaO comparison yield in fluorescence analysis limestone. The process comprises the following steps: a, ensuring that any object is not arranged in a range of 10cm around a balance; b, adjusting the spectral shift; and c, stirring uniformly, wherein after the adjustment, the limestone comprises the following components in parts by weight: 52.13 parts of CaO, 12.4 parts of SiO2, 2.28 parts of Al2O3 and 1.23 parts of MgO. According to the process capable of increasing the CaO comparison yield in the fluorescence analysis limestone, disclosed by the invention, the defects such as large weighing errors, high spectral shift and stirring non-uniformity in the prior art can be overcome, so that the advantages of small weighing errors, low spectral shift and stirring uniformity are realized.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a process capable of improving the pass rate of fluorescence analysis of limestone CaO comparison. 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, th...
