PANalytical


Turnkey solution for accurate XRF bead analysis of cements, clinker, raw meal, limestone, clays and gypsum using CEMOXI fused bead standards set

For process control of a cement plant the elemental composition of raw materials, raw meal, clinker and cement needs to be measured accurately on a continuous basis. These analyses have direct consequences for production process parameters like feed speeds, kiln temperatures, grinding times etc. Optimizing these parameters minimizes production costs. Moreover, accurate analyses also assure product quality and consistency.

XRF spectroscopy has become an established analytical method for quantifying the elemental composition of cement and cement-related materials. XRF delivers important advantages, such as straightforward sample preparation, accurate and reproducible results and highly automated analysis. XRF reduces measurement times to a matter of minutes and allows routine analysis to be carried out by factory operators. For accurate analysis, certified standards are essential. The CEMOXI standards set, which is produced from high-purity chemicals, provides very accurate concentrations. These are traceable, bringing the method closer to being a primary analytical solution. The CEMOXI standards set is suited to a wide variety of materials, including cements, clinker, raw meal, limestone, clays and gypsum.
