Report to Congress on Cement Kiln Dust: Alternative

Additionally, the fuel value of the CKD is lost when the dust at elevated temperatures is removed.1Lastly, removing CKD from the system imposes handling, transportation, and disposal costs. Hence, the first efficiency goal of the kiln operator should be to remove less CKD from the kiln system when possible.

Cement Kiln Dust (CKD): Characterisation and utilisation in cement

Cement kiln dust (CKD) is a by-product 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.
