Periclase in chrome-magnesite lining of rotary kiln for firing cement clinker

Cement clinker was produced in laboratory using the same ingredient as actual production, comparing with the ones which incineration residue of glyphosate waste mother-liquor was added in. The products were characterized by XRD, and the results showed that the main constituents were not changed. And some of the main performances were tested according to GB standards. After the residue was added in, the water requirement of normal consistency remained no change as 26%; the setting time, both initial set and final set, was extended; the soundness was improved a little. And it could be inferred that within a certain range, the more the residue added in, the longer the setting time was, the better the soundness was. According to all the results, using rotary kiln to dispose the waste mother-liquor was feasible in the actual production.

All the desired properties of cement primarily depend on the physicochemical characteristics of clinker from which the cement is produced. The mineralogical composition of the clinker forms the most important parameter influencing these properties.Optical microscopy provides reasonably accurate information pertaining to the thermal history of the clinker, while XRDA still remains the proven method of phase identification, and bulk chemical composition of the clinker can be readily obtained from XRFA. Nevertheless, all these microanalytical techniques are somewhat limited in their applications, and SEM/EDXA combination fills this gap uniquely by virtue of its high resolution imaging capability and possibility of instantaneous chemical analysis of individual phases.Inhomogeneities and impurities in the raw meal, influence of kiln conditions such as sintering and cooling rate being directly related to the microstructure can be effectively determined by SEM/EDXA. In addition, several physical characteristics of cement, such as rhcology, grindability and hydraulicity also depend on the clinker microstructure.
