Problems solved by technology

[0003] In 2012, we found that the fluctuation of the raw material was large, and the qualified rate was low. In view of these situations, in order to better do the batching work and cooperate with the production, it is necessary to improve the qualified rate of the raw material
[0013] There are many faults in the mill and tablet press; the raw meal sample is dusty; the grinding aid triethanolamine has a great influence on the chemical composition of the raw meal
[0014] In the process of realizing the present invention, the inventor found that there are at least defects such as high failure rate, poor stability and unreasonable proportioning in the prior art

Embodiment 1

[0065] Implementation 1. In view of the problem of many failures of mills and tablet presses, we have conducted an analysis:

[0066] It was found that the bottom of the disc grinding seat was fixed by several screws. Due to the daily vibration, the screws became loose or even broken, causing disc grinding and dust running. We welded the bottom of the disc grinding seat, so there will be no more loose screws; at the same time, we found that the tablet press caused the sample to crack because the pressure of the tablet press was not enough. Therefore, we found out the appropriate pressure through experiments and comparisons for specific mills. ; When the mold is damaged and cannot be used, contact the manufacturer to repair and replace the mold.

[0069] Depend on Figure 7 It can be seen that from January to July 2012, the operation rate of the mill and tablet press before the activi...

Embodiment 2

[0070]Implementation 2. We analyzed the problem of low fluorescence operation rate:

[0071] The raw material sample is dusty because the vacuum cleaner failed to clean it in time, resulting in insufficient suction of the vacuum cleaner. When the raw material was detected, the spectrometer could not accurately analyze the actual strength of each element in the material, which directly caused the fluctuation of the ingredients. Therefore, We arrange specific post personnel to clean the vacuum cleaner every day. When the vacuum cleaner is normal, if powder samples are found around the steel ring of the raw sample and on the surface of the sample, the post personnel will be subject to financial penalties.

[0074] Depend on Figure 8 It can be seen that from January to July 2012, the operating rate of the spectrometer before the event was low, with an average of 82.50%, and the flu...

Embodiment 3

[0075] Implementation 3. We analyzed the problem that the grinding aid triethanolamine has a great influence on the chemical composition of the raw meal:

[0076] Research has found that grinding aids have an impact on the strength of elements in raw meal samples. Therefore, we must control the amount of triethanolamine added within a certain range, and the biggest factor that affects the constant amount of triethanolamine added is the breakage of the burette and the post personnel. In this regard, we require that once the burette is damaged, the post must be replaced immediately, and the correct method of adding triethanolamine must also be practiced during the post assessment.

Abstract

The invention discloses a method for improving a contrast qualified rate of a fluorescence analysis raw material, wherein the method includes the steps: a, adjusting a mill; b, adjusting a spectrometer; and c, regularly screening a burette, and adjusting a formula of a grinding aid, wherein the adjusted grinding aid comprises the components in parts by weight: 0.05 part of triethanolamine, 0.02 part of Grace SCJ809, 0.01 part of Altwell AD-E8223, 0.07 part of Zongsen D-2, and 0.06 part of Honghai HGA620. The method for improving the contrast qualified rate of the fluorescence analysis raw material can overcome the defects in the prior art of high fault rate, poor stability, unreasonable ratio and the like, so as to realize the advantages of low fault rate, good stability and reasonable ratio.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a method for improving the pass rate of raw meal 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, this method is used in the analysis of limestone, sand shale, raw meal, clinker, cement and other samples in our company. Therefore, the accuracy of fluorescence inspection will indirectly affect the quality of the factory cement. Therefore, fluorescence analysis is an important part of the entire cement production control is particularly important in the process. [0003] In 2012, we found that the fluctuation of the raw material was large, and the qualified rate was low. In view of these situations, in order to better prepare the...
