Typical Chemical Position Of Cement Kiln Dust

Abstract Cement kiln dust CKD is a byproduct of the cement manufacturing process. Despite the fact that usually its composition is similar to partially calcined raw feed, the variability in raw materials, fuel, type of process, dust collection systems and product specifications influence both the physical and chemical characteristics resulting in a highly variable material.
