Sampling free on-line analysis in air slides
SpectraFlow using SOLBASTM technology now permits the analysis of raw meal from the raw mill in air slides, without sampling stations and XRF analysis in the laboratory. The system is designed to use the available control openings in the air slide and is a viable alternative to the standard automatic sampling systems for process optimization.
Once the material for the cement making process has passed the raw mill, its standard means of transportation is normally the air slide. From then on samplers are used to get the material out of process flow and the samples are transported to the laboratory for XRF analysis. Today very elaborate solutions exist for the automatic sampling, homogenizing of the samples, transport of the sample and its analysis by XRF. They can make batch sample analysis results available at rather short intervals, which, if the control software takes proper care of the time gaps between the samples, can be used...
