RAW MEAL FOR CEMENT PLANT

Cement Raw Mill in Cement Plant for Cement Raw Meal

Cement raw meal is a mixture of various raw materials before cement calcination. It is a mixture of lime raw material (mainly composed of calcium carbonate), clay raw material (aluminosilicate containing alkali and alkali soil) and a small amount of calibration raw material in a certain proportion and ground to a

Raw materials for cement manufacturing

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.
