raw meal cement production

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
