The burning zone temperature (BZT) in cement rotary kiln is a mostly important index which affects the quality of produced cement. In rotary kiln, the bilateral movements of air and complex

Thermal analysis of spurrite from a rotary cement kiln

A number of samples from the pre-burning zone of a wet-process cement rotary kiln were examined by combined DTA/TG and XRD for estimation of spurrite (2Ca2SiO4 CaCO3). It was found that decarbonation temperatures of spurrite range from 1130 to 1190 K and they are 45 to 75 K higher than that of calcite occurring in the same sample
