Raw meal typically contains 78-80 CaCO3 so that lime- stone can only fall close to this level to the extent that it also contains the other ingredients. It is essential to have sufficient flux/liquid (Al Fe Raw meal typically contains 78-80 CaCO3 so that lime- stone can only fall close to this level to the extent that it also contains the other ingredients. It is essential to have sufficient flux/liquid (Al Fe Mg F) to promote fusion in the kiln but MgO should not exceed 4-5 or the cement may be expansive.

This meant that for the first time there was virtually no limit on the fineness that could be achieved. From the early 1900s both for cement grinding and for grinding hard raw materials whether by This meant that for the first time there was virtually no limit on the fineness that could be achieved. From the early 1900s both for cement grinding and for grinding hard raw materials whether by wet or dry process the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm) followed by a tube mill for fine grinding. The heated raw meal now enters the kiln where the gas temperature exceeds 2000 °C where it is transformed into a molten mixture inside the rotating kiln. At the temperature of 1450 °C the The heated raw meal now enters the kiln where the gas temperature exceeds 2000 °C where it is transformed into a molten mixture inside the rotating kiln. At the temperature of 1450 °C the minerals in the raw meal undergo chemical reaction to form a new compound known as Clinker which is the pre-curser for the production of cement.

Denmark (trade named Cemax Mill). Horomill is suitable for grinding raw meal cement and minerals whereas Cemax Mill is mainly for cement grinding. The mill can be used for pre-grinding and finish grinding. This mill-system claims to have advantages of ball mill roller mill and roller press in terms of reliability and energy savings.

Pressed pellets of cement raw meal sample milled with different grinding aids (graphite aspirin and lithium borate) were subjected to XRF. Graphite produced better particle size uniformity with a corresponding standard deviation that made quality control of raw meal easier and better than aspirin and lithium borate.
