EXPERIENCES ON REDUCING CEMENT KILN STOPPAGES DUE TO INCORRECT UTILIZATION OF KILN RETURNED DUST

incorrect utilization of cement kiln returned dust not only can produce variations in kiln operation conditions, resulting in the corresponding undesirable consequences such as decrease in clinker quality, but also may lead to the enhancement of volatiles circulation and the subsequent repeated kiln stoppages due to the phenomenon of cyclone jamming. The importance of regulating the amount of returned dust content of kiln feed should be considered since higher contents of volatile constituents in kiln returned dust along with their considerably higher volatilities compared to the corresponding fresh kiln feed are liable factors for the enhancement of volatiles circulation.
