The basic cement kiln system comprises a preheater in which feed material is prepared by heat exchange with hot exhaust gasa fired rotary kiln in which the clinkering reactions occur and a cooler in which the hot clinker exchanges heat with ambient combustion air.
The thermal behavior of the SF cooler (e.g. heat balancerecuperation) is similar to the other grate coolers. Process Technology B05 - PT II C01 - Kiln Systems Clinker Coolers 3. GRATE COOLERS 3.2 The Cross Bar Cooler 3.2.2 Main features 3.2.2 Main features One inclined fixed grate.

The heated air from the coolers is returned to the kilnsa process that saves fuel and increases burning efficiency. After the clinker is cooledcement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains.
In addition the cooler should be less complicatedmore efficient and easier to operate than other grate coolers on the market. Sealing air is eliminated and the distribution of air is optimized for all modes of operation The thermal behavior of the SF cooler (e.g. heat balancerecuperation) is similar to the other grate coolers.
Aug 171971 Classification Code (SCC) for portland cement plants with wet process kilns is 3-05-006and the six-digit SCC for plants with dry process kilns is 3-05-007. Portland cement accounts for 95 percent of the hydraulic cement production in the United States. The balance of domestic cement production is primarily masonry cement. Both of these
From a cement performance viewpointfaster cooling of the clinker enhances silicate reactivity. The cooled clinker is then conveyed either to the clinker store or directly to the clinker mill. The clinker store is usually capable of holding several weeks supply of clinkerso that deliveries to customers can be maintained when the kiln is not

Heat loss distribution across different elements can be established through heat balance and process audit of pyro section. Fuels used commonly to provide heat for the conversion processes are coalfuel oiland natural gas. Alternative fuels like petcokerubber tyreswood chipsetc. have been introduced to economize cement making process.
Analysis of energy balance was used to determine the sources of heat loss from kiln system. The major heat loss is Heat losses by the kiln exhaust gas (19.15%) Hot air from cooler stack (5.61%
The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110 C 120 Ccooling to below 80 C is necessary to avoid this reaction.
