In the cement production process, the chemical composition and mineral composition of raw materials, cement raw materials and cement clinker must be determined in real time to control and optimize the process and ensure product quality.
Accurate analysis of the elemental composition of raw materials, cement raw materials, cement clinker and cement products in the cement production process is particularly important, which is very important for promoting the production process in the most cost-effective manner to obtain the highest product quality.
Chemical analysis methods are cumbersome and inefficient and cannot meet the requirements for real-time monitoring of quality and real-time adjustment of ingredients. The large-scale wavelength-dispersive X-ray fluorescence spectrometer used in the cement industry in recent decades has greatly improved the analysis efficiency and precision, but such X The ray fluorescence spectrometer has high requirements on the operating environment, and the cost of its operation, maintenance, and repair is extremely high, which causes great pressure on the testing cost of the cement industry.
The new generation of high-sensitivity X-ray fluorescence spectrometer developed and manufactured by ANCOREN is characterized by high precision and miniaturization. At the same time, its maintenance and repair costs are very low, and it fully meets the requirements of national standard "GB/T 176 cement chemical analysis The requirements of the "Method" . The success of development and manufacturing has greatly improved the level of detection of elemental content in the cement industry.
