cement kiln dust recycling

A method of recycling cement kiln dust (CKD) generated during the direct manufacturing of cement. The recycling process utilizes the creation of a flowable slurry comprising CKD, a process aid, optionally other raw materials and water. The process aid is selected from the group consisting of sucrose, raffinose, lignin, methylglucopyranoside, lactose, fructose, sodium polyphosphate, trehalose

May 24, 2002 Excessive amounts of alkalies can have deleterious effects upon the process of cement manufacture and the product. Normally much of the alkali present in cement raw materials is volatilized in the cement kiln and condenses on the particles of kiln dust which are carried out of the kiln by the combustion gases. Air pollution control devices, such as electrostatic precipitators and fabric

Apr 19, 2013 Recycling kiln bypass dust into valuable materials. Abstract: A new process has been developed for processing chlorine-bypass-dust into new materials that can be sold or used in the cement kiln. Bypass dust is the dust that is rejected from a kiln system in order to lower the chlorine or alkali content of the produced clinker

Scrape wet kiln dust or cement and place in container. Allow material to dry or solidify before disposal. Do not wash kiln dust down sewage and drainage systems or into bodies of water (e.g. streams). Methods for Cleaning Up: Avoid actions that cause dust to become airborne during clean-up such as dry sweeping or using

Kiln dusts are fine by-products of Portland cement and lime high-temperature rotary kiln production operations that are captured in the air pollution control dust collection system (e.g., cyclones, electrostatic precipitators, and baghouses). Cement kiln dust (CKD) is a fine powdery material similar in appearance to Portland 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

May 22, 2008 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
