Quality control of cement, from crushing tol analysis
To produce high-quality cement, the mineralogical and chemical composition of raw materials as well as intermediate and finished products has to be determined. At each stage of the production, samples have to be taken, processed and analysed to ensure quality control without gaps.
RETSCH offers a range of instruments suitable for sample preparation during the complete production process, from the quarrying of the raw materials to the final product. The typical sample preparation process involves preliminary size reduction, sample division and fine size reduction before the sample can be submitted to further analyses.
Elemental analyzers using combustion technology are ideally suited for the fast, accurate and reliable determination of carbon and sulphur in cement. Apart from size reduction, no further sample preparation is needed. ELTRA’s elemental analyzers measure the concentrations of carbon and Sulphur from ppm levels up to 100%.
