Özet

Within the study, the results of the test works performed around a cement grinding circuit in order to select the most appropriate option are presented. In this context, sampling campaigns were arranged with different grinding aids and mixed products then the influences were discussed by considering the changes in production rate, equipment performance, energy consumption, cement quality and clinker saving parameters. The results implied that the production rate of the circuit and the 28-day strength of the cement could be increased by 24% and 3.5% respectively with the selection of an appropriate chemical. In addition, the use of chemicals may reduce the clinker consumption by 5% that is important regarding to CO2 emissions. The studies concluded that triethanolamine based chemical had better performance parameters than the other types. (c) 2014 Elsevier Ltd. All rights reserved.
