Cement and Raw Materials (XRF & XRD)
In cement production the chemical and mineralogical composition of raw materials as well as intermediate and finished products has to be determined to control and optimize the process and to guarantee constant high product quality. The raw materials from the quarry, additives, like slag, filter dust,.., through all steps of the production process (milling, mixing,..), the intermediate products, e.g., clinker, hot meal, and the final products are analyzed directly. This information is important to drive the process in the most cost effective way for highest quality. In close partnership with the cement industry Bruker AXS is continuously pushing the performance of its analytical solutions. We are committed to strongly focusing on the seamless integration of our XRF and XRD tools into the process and on simplifying the analytical tasks. Our precalibrated solutions in combination with software for easy, safe, reliable and intuitive operation are trend-setting.
Wavelength dispersive X-ray fluorescence (WDXRF) for process and quality control
- S8 TIGER
One of the most advanced analytical techniques for process and quality control in Cement is wavelength dispersive X-ray fluorescence analysis (WDXRF). No other technique can compete with the accuracy and precision, the ease of use, the simple and fast sample preparation and finally the high grade of automation and integration into any process control strategy.
The S4 PIONEER, the high performance, high sample throughput wavelength dispersive X-ray fluorescence spectrometer (WDXRF), combines analytical flexibility for routine analysis and any analytical task beyond routine with high performance.
The S8 TIGER 1K is the perfect wavelength dispersive X-ray fluorescence spectrometer (WDXRF) due to the unique “Plug ‘n Analyze” technology, when installation requirements and running costs are the main focus.
The S4 PIONEER and S8 TIGER 1K in combination with PETRO-QUANT are the perfect analytical solutions for the analysis of hazardous elements in secondary fuels: Reliable safe liquid handling, calibrated for the accurate and precise standardless determination of elements in hydrocarbons: Trace analysis in secondary fuels has become an easy job in daily routine.
Process Control with energy dispersive X-ray fluorescence Analysis (EDXRF)
Due to the importance of continuous process control there is need for a backup instrument as replacement for every wavelength dispersive X-ray fluorescence spectrometer (WDXRF) in maintenance- and service-times, which can be setup in short time.
The S2 RANGER (EDXRF) is setting a new standard with the user interface based on intuitive touch screen operation for easy use and improved analytical performance with consequent integration of latest technologies.
True phase analysis of clinkers and cement with X-ray diffraction
- LynxEye Detector
The physical and chemical properties of clinkers and cement are not only determined by the chemical composition. They are mainly governed by the mineralogical (or: phase) composition. Traditionally clinker phase analysis is done by the BOGUE calculations or by clinker microscopy. However these methods are well known for their deficiencies, but until recently there haven’t been any other tools available.
The introduction of our unique TOPAS software leaded to the worldwide breakthrough of a new analytical tool for quality and process control in cement industry. Fully automated phase analysis of clinkers and cement is now established by X-ray diffraction and the so called Rietveld method. Additionally detector developments reduced measurement time to minutes, enabling real process control. Bruker AXS´s high-throughput diffractometer D4 ENDEAVOR, combined with the Super Speed detectors and the outstanding TOPAS software, brings the fastest and most reliable solution for quantitative phase analysis to the cement industry.
TOPAS – unrivalled performance for quantitative Rietveld analysis
TOPAS’ speed of calculation and the stability of this new generation of refinement software is the decisive step to overcome the limitations of traditional Rietveld programs. The seamless integrated Fundamental Parameters Approach (FPA) allows a physically correct description of the measurement data, which finally ensures getting accurate analytical results. There is no need for a reference measure. It is not only the most successful Rietveld software, it is meanwhile the scientific and industrial standard in the world of cement.
