DIFFRAC.DQUANT: Control of free lime content in clinker

XRD Application Report

DQUANT Free lime in clinker, Application Report

In the cement plant the control of free lime is the most basic but sound base for enormous cost savings during kiln operation. The classic calibration method implemented in DIFFRAC.DQUANT provides accurate and precise quantitative phase analysis.


Quantitative phase analysis by X-ray powder diffraction is used for the determination of clinker mineralogy in cement production. The free lime content is a direct indicator of the kiln performance. Decreasing the kiln temperature while burning at softer conditions directly decreases fuel consumption.


Furthermore, it extends the refractory’s life-time in the kiln, thus decreasing maintenance costs and down-times. Lower burning temperatures reduce emissions contributing to a cleaner environment.
