RAW MATERIALS' CLINKER BURNABILITY VS. OXIDES ACIDITY/BASICITY

Reactions that conclude to clinker formation from raw raw materials can be, basically, considered as taking place between oxides, and are of an add-base nature. A straightforward hypothesis can follow: the basicity gradient between oxides which is an intrinsic attribute of the raw meal determines from a chemical viewpoint the raw mixes bumability. This feature, along with the Lime Saturation Factor, LSF, influences both reactions' kinetics and the degree of transformation of the reactants in reaction products. In this paper, a series of correlations between bumability and basicity gradient and LSF were extracted; in that purpose, there were used several series of foreign and Indigenous raw meals. The analysis of the results confirmed the starting hypothesis.
