Achieve constant, high-quality cement

Building materials

How to guarantee a constant, high-quality cement?

In order to guarantee a constant, high-quality cement, control of the production at every stage is of the utmost importance. These stages include the production of raw meal, the preparation of kiln feed and the production of clinker through to the final mixing of the end product. At every stage process control is possible by chemical and mineralogical analysis. The latest demands on reducing CO2 emissions drive the use of alternative fuels and the production of blended cements. Here, chemical and mineralogical analyses of the intermediate and final products as well as fuels become even more important. This requires reliable and rugged solutions to steer the process in the most cost-effective way for the highest quality cement or concrete. PANalytical offers solutions that meet these demands and seamlessly integrate into the production process.

Stockpile management and raw meal preparation

How to achieve a constant, high-quality feed of raw material?

A constant, high-quality feed of raw material into the production process requires careful blending of material sourced from various locations in the quarry. The key parameter of this stockpile management is its chemistry. Also the composition of additives (such as Al, Fe and quartz) and possible impurities must be monitored carefully to guarantee a high-quality end product.

PANalytical’s compact benchtop instruments are widely used for elemental analysis of drill meals or for raw material screening. They are easy to install and require no liquid or gas supplies,  therefore maintenance costs are low. In addition the Epsilon 3XLE complies with the ASTM C114 norm.

Calcination and clinker production

How to comply with emission regulations?

In view of the control and required reduction of CO2 emissions during calcination and clinker production, process control becomes even more critical and the need of accurate and rapid analysis of the elemental and mineralogical composition is even more important. For example, CO2 emission regulations drive the use of alternative fuels in the kiln. However, there is also the need to detect toxic heavy elements and to control their emission. Furthermore, the ash content of the fuels also affects the final composition and quality of the clinker and analysis is needed to improve product consistency.

PANalytical’s compact benchtop instruments are suitable for heavy elemental analysis of clinker. They are easy to install and require no liquid or gas supplies, therefore maintenance costs are low. In addition the Epsilon 3XLE complies with the ASTM C114 norm

Application notes:

Grinding and mixing

How to control the quality of the different cement types?

In the final phase of the production process, various additives to the clinker produce various types of cement. PANalytical’s compact benchtop instruments are ideal for monitoring gypsum or slag additions. They are easy to install and require no liquid or gas supplies, therefore maintenance costs are low. In addition the Epsilon 3XLE complies with the ASTM C114 norm
