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

2018-3-1 A Norwegian cement plant producing about 1.3 million tons of cement per year was used as a case study. A mass and energy balance was made for the raw meal department, and process data available from the plant process database as well as manually measured gas flow rates were used to calculate the available heat.

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.
