Suppression of PCDD/Fs by Raw Meal in Cement Kilns

Likewise, the contents of Cu and Cl in the raw meal were 0.0012 and 0.033 wt. %, respectively. There was no need for the extraction of the raw meal since the initial concentration of PCDD/Fs did not exceed 0.02 ng g –1. Experimental Set-up Fig. 1 illustrates the experimental set-up used to replicate the commercial cement plant co-processing MSW.

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.

Raw materials - Understanding Cement

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
