Then the cement is stored in different cement silos depending upon the type of MILLS Nearly 45% Gypsum is to be added along with clinker and interground to a fine powder called "CEMENT".
New type of clinker significantly reduces CO 2 emissions. Cement clinker production is very energyintensive — around tonnes of CO 2 on average are released per tonne of clinker manufactured. We are therefore making a huge effort to improve the CO 2 balance sheet of our production operations.
The clinker cooler exhaust fan plays a critical role in the cement making process. Raw mix enters the kiln and is heated to 1,450 degrees Celsius where it is transformed to clinker. Upon exiting the kiln, the clinker is cooled to 100 degrees Celsius by the clinker cooler fans which blow cooling air through the clinker.
The process that includes, rapidly quenching finished hot Portland cement clinker by admixing with the clinker a Portland cement raw mixture at a rate such that the potential Portland cement quantity of the raw mixture corresponds substantially to the quantity of clinker admixed therewith.
The rotary kiln is part of rotary drum equipment. This kiln is mainly divided into oxidation pelletizing rotary kiln and metallurgical rotary kiln. The rotary kiln includes support device, shell, driving device, sealing hoods of head and tail, cooler, and etc. Intelligent centralized lubrication system makes centralized control possible.

The heart of the cement manufacturing process is the thermal process in the kiln system with clinker capacities of up to 12,000 tonnes per day nowadays. A kiln system consists of a static preheating system with typically five cyclone stages and a precalciner.

Clinker Cooler and PreHeater Dedusting The control of clinker fines emissions after the heatexchanger, placed downstream of the clinkercooler, is usually a problem for cementplant managers . The process is characterized by high material abrasiveness, high loads and variable flow rate in normal and maximum conditions.

The study focuses onthe thermal performance of the clinker cooling system in a cement production plant employing the dry process. The aim is to study how the operational parameters, cooling air input rate and temperature, clinker input rate and grate speed, affect the energetic and exergetic performance of the clinker cooler.
The fuel is ignited and burned out in the combustion zone. The sintering process and the formation of clinker occur inside the kiln. Hot clinker is cooled in the cooler. Ambient air is used to cool the clinker and partially used for coal combustion. The cooled clinker is stored in the clinker yard/clinker silo for cement grinding.
The model describes the clinker burning process from the kiln meal feed to the discharge of clinker from the cooler, and consists of individual models for preheater, calciner, gas offtake (bypass), rotary kiln and grate cooler.
ControlFlow Grate Cooler, clinker grate cooler, Grate cooler mechanical in cement plant . Grate cooler is a major mainframe equipment of cement clinker burning system. The cooler mechanical main function is cooling and transporting the cement clinker and providing rotary kiln and decompressing furnace with hot gas.
calcium that comprise the Portland clinker (SC BAT Cement, 2008). Basically, the clinker production process consists of the clinker burning as such (preheating, kiln firing process with or without precalcination, and with or without a kilngas bypass) followed by the clinker cooling.
MOMTAZAN CEMENT FACTROY kiln is capable of producing 3300 tons of clinker per day and is working 24/7 nonstop. Clinker Cooler: The output of the kiln is clinker with a temperature of up to 1100 degrees C, which must be cooled appropriately in order to safeguard the phases.

Greater Detail: Cement Plant Operations Handbook, Pages 3945 Crewmen's Guide, Clinker Production, Precalciner, Page 32 (82) Preheaters In the 1930s, significantly, in Germany, the first attempts were made to redesign the kiln system to minimize waste of fuel[5].
in the cement industry St. Marys Cement Group is a whollyowned subsidiary of Votorantim Cimentos, a familyowned international cement manufacturer based in Sao Paulo, Brazil. Its Bowmanville plant near Toronto, Canada, produces approximately million tons of clinker and million tons of Portland cement annually.
Cooler exhaust fans move ton of exhaust air per 1 ton of clinker production. This process is a part of air blown into the cooler by cooling fans that are not useful for fuel combustion.
