Research on Kinetics on Magnesium Slag Calcining to Produce Cement ClinkerZAN He-ping1,ZHAO Hai-jin1,2,GAO Jian-rong1,2,SUN Su-zhen1,YU Yan-mei1(1.Material and Engineering Department,Shanxi Vocational Polytech College,Taiyuan 030006,China;2.Xi'an University of Architecture and Technology,Xi'an 710055,China)The method of raw material burnability is used in the experiments in this paper.With the aids of Gentling and Arrhenius equation,reaction rate constant and apparent activation energy of clinker formation reaction is calculated. And mineral compositions of magnesium slag are measured by using XRD.The results show Magnesium slag can be used to calcine cement clinker as material.and can remarkably reduce apparent activation energy and temperature of clinker formation reaction,quicken formation of clinker mineral and shorten sintering time.magnesium slag;batching;calcination;reaction kinetics
