2021-7-13 · The recovery and reuse of this iron and coke is very important with increasing price of conventional resources. Cement plants on the other hand are looking for alternative fuel and raw materials as a substitution to the traditional fuel and raw materials, thus co-processing of the flue dust is a solution for both the industries.
2008-5-22 · Cement kiln dust (CKD) is a significant by-product material of the cement manufacturing process. Over the past several years dramatic advances have been achieved in the management and use of cement kiln dust, thus reducing its dependency on landfill disposal. Sustainability is the cornerstone of the cement industry, not only in the products ...
2021-7-6 · Cement kiln dust (CKD) is a fine-grained solid by-product generated during the cement manufacturing process and captured by the facility’s air pollution control system. Because much of the CKD is unreacted raw materials, it is often returned to the production process.
