Homogenization (BLENDING) Cement Plant

Homogenization (BLENDING) In preparing raw meal, raw materials like limestone, clay and iron ore are proportioned and fed to raw mill, where these raw materials are ground and well mixed. However, this mixing is not enough to produce clinker of uniform quality. For stable kiln operation and to obtain uniform quality of clinker it is necessary to

A System for the Control of the Homogenisation of

Control of the homogenity of the ground mix of the raw materials before feeding it into the kiln is a very essential problem in cement manufacture. Earlier, time-consuming and laborious wet chemical methods were the only means for determination of the CaCO 3 content at this stage of production. In recent years X-ray fluorescence technique has, however, achieved ever increasing use as a faster method for the control of the process.
