Dec 26, 2019 Various material characteristics play a part in how the material is going to perform in the kiln, and subsequently, how the kiln is to be designed around the material to accomplish the process goal. The following provides an overview of some of the normal material characteristics which can influence the design of the kiln.
Hot gases coming from the kiln are sucked through the raw nodules on the grate, preheating the nodules. Dust emission from cement kilns can be a serious nuisance. In populated areas it is usual and often compulsory to fit cyclone arrestors, bag-filter systems, or electrostatic dust precipitators between the kiln exit and the chimney stack.
phasis on design characteristics has resulted in good operating ex-perience with the baghouse. To make cement clinker, the primary materials of clay and limestone are quarried near Alpena and transported to our mills where the materials are dried, crushed, and pulverized before being fed into our coal-fired kilns. In the kilns the

Cement kiln dust, a waste byproduct, is generated during the manufacturing of cement clinker. During clinker production in a kiln, volatile components such as sulfates, alkalis K 2 O and Na 2 O, chlorides, etc., are drawn toward CKD and make it alkaline, thus restrict CKD reuse in a cement kiln. Huge amounts of CKD are dumped in landfill ...
The characteristics of the soil investigated were the unconfined compressive strength, California bearing ratio CBR and swell potential. It was observed that adding cement kiln dust to the Philadelphian clay significantly improved the aforementioned properties.
Another method for treating cement kiln dust is described in Patzias U.S. Pat. No. 2,991,154, July 1961 wherein kiln dust is mixed with water in a ratio of 2.5 to 3 parts water to 1 part dust, with the resulting mixture heated to about 358 F. in a closed vessel at a pressure of 150 psi for about 30 minutes.
