This process is repeated a number of times typically three to six by stacking "riser" ducts and cyclones on top of one another in a tower. By repeated heat exchange, most of the heat in the kiln exhaust gas can be captured, while heating the rawmix to calcination temperature. Such heat as escapes the preheater is used to heat the rawmill.
CTLGroup was retained to evaluate the extent of cracking in the concrete from of a 326ft tall, sevenlevel preheater tower, and formulate a repair plan on a fasttrack basis. CTLGroup mobilized at the site in less than 24 hours and performed an initial structural safety assessment. A comprehensive structural evaluation indicated that the structure required [.]
Evaluation and Structural Retrofitting of a Cement Plant Preheater Tower. Inspection by plant personnel revealed cracking in the concrete frame of a 326fttall, 7level preheater tower. Onsite plant engineers deemed the cracking significant, especially since the structure supports critical manufacturing process equipment.
PREHEATER TOWER Achieve capacity and energy benefits in your preheater. The design of the preheater system is a major factor for efficient cement production. Its design and complexity have evolved rapidly thanks to growing production volumes and increasing energy costs. Today''s dry process kilns, coupled to multiplestage preheater systems, offer 20 times more capacity than ...
The preheater tower supports a series of vertical cyclone chambers through which the raw meal passes on its way to the kiln. To save energy, modern cement plants preheat the meal before it enters the kiln. Rising more than 350 feet, hot exit gases from the kiln and clinker cooler combined with fuels such as ground coal, petcoke, natural gas ...
Kiln preheater towers provide heat transfer from hot gases to kiln feed material. The counterflow of gases and material takes place in cyclones, referred to as stages, in the preheat tower. As material flows from the top to bottom of the tower, it is exposed to increasingly higher temperatures as it .

Two buildings, the cement mill and the prehomogenisation tower in AGET Herakles, Lafarge plant in Volos, had to be upgraded to earthquakes. The mill building has a height of about 50 meters and its neighboring building, the prehomogenisation about 66 meters, were made of reinforced concrete in the 70s and are separated by a joint.
PREHEATERS SDD CP002 01/10/2013 Ver. Page 3 of 45 Page 3 . The basic cement kiln system includes a preheater in which raw material is prepared by heat exchange with hot exhaust gas. In this way, temperature rises from the ambient value at the preheater inlet to about 800900° at the kiln inlet, thereby producing a calcination effect.
