Innovative real-time/on-line cement materials analyzer

摘要

This paper will fix on the NIR part of the IR spectrum used in SOLBAS~? technology. Thanks to computer filtering techniques, the technology is simple to use and has been shown to be highly reliable. NIR has the advantage of probing bulk materials with no requirements for sample preparation. The speed of scanning (<100 milliseconds) and resultant generation of robust spectral bands provide the means for characterization of chemical oxides and mineralogical polymorphs in virtually any material. Common high-intensity lamps are sufficient sources of broadband infrared radiation in specially configured illumination systems for these analytical applications. Lengthy tests at actual cement plants have successfully demonstrated the reliability, repeatability, and accuracy.
