Clinker cooling is a key step in the pyroprocessing system. The cooler is essential for recuperating heat from the clinker and cooling it sufficiently for the cement milling operation. However, the primary objective of the cooler is to transport hot clinker from the kiln. During this process, the ...
The clinker manufacturing process Al badia cement. The clinker manufacturing process. The clinker manufacturing process starts with the extraction of the raw meal from the homogenization silo to insure that the raw meal is stable and homogenized in order to produce consistent clinker quality.
With more controlled processes thanks to process instrumentation, cement producers can help ensure a healthier environment for future genera tions. SITRANS LR560's highly durable polyetheramide lens antenna and narrow four degree beam angle make it ideal for level measurement in clinker production.
Clinker cooler bed depth Reliable level measurement of the clinker bed depth allows accurate control of the clinker cooler, which results in a more stable cooling process. Next to a more consistent clinker quality, this also has a positive influence on the operation of the kiln and the fuel consumption. Preferred device: SITRANS LR560
Objective: Pyro process is the most important process in a cement plant, and clinker quality is almost the final product (cement) quality. Additionally, productivity of the pyro process system determines the productivity of the plant. Cost incorporated in the pyro process affects greatly that of the plant.
In general, rapid cooling of the clinker in the hightemperature range reduces the water requirement of the cement. With sulfateoptimized cement, the faster cooling is all the more advantageous for the solidification behavior and the strength development of the cement, the higher the C 3 S and C 3 A content of the clinker is.
May 03, 2018· The typically ambient air utilized in the clinker cooler 25 absorbs heat from the clinker. A portion of the thus heated air from the clinker cooler is directed into kiln 24, and from there to kiln riser duct 27 for diverting the kiln exhaust gases from the rotary kiln and from thereafter into the precalciner 23.
clinker cooling system in cement Process Coolers for Cement Clinker | Ammermann Partners The air flow through the clinker purges fines from the clinker bed to the surface of the clinker.
c. Clinker Cooler Storage. Early systems used rotary coolers, which were rotating cylinders similar to the kiln, into which the hot clinker dropped [8]. The combustion air was drawn up through the cooler as the clinker moved down, cascading through the air stream. In the 1920s, satellite coolers became common and remained in use...

The aim of any cooling system is to cool the clinker as quickly as possible, to set and maximize C3S content. Simultaneously, it is important to capture and reuse the heat liberated by this process. In the grate cooler, the clinker enters at a temperature of around 1,200°C, rapidly spreading its heat into the grate and surrounding refractories.
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. This is performed in the grate cooler by applying cool air current.
The fine microstructure of cement clinker provides a number of clues relating to the state of the process which made it, including the temperature, the chemistry, the fuel type and quality, the thermal profile through the process and the efficiency of cooling. Microscopic and macroscopic analysis ...
SsangYong Cement orders clinker cooler upgrade from Claudius Peters. South Korea: SsangYong Cement has awarded a contract to Claudius Peters Projects for the supply of a grate cooler modification. The existing cooler at the Donghae cement plant will be .
In conventional white cement manufacturing process the white clinker formed from a kiln is discharged to a decoloriser or quencher for water quenching. The white clinker is cooled in a decoloriser with the help of water in the absence of air to avoid deterioration in whiteness.
Five fire hazards associated with the cement manufacturing process are outlined in the following sections. 1) Coal Storage. On average tonnes of coal are consumed in the kiln per kilogram of clinker cement production. As such coal storage during cement manufacturing is an important component to consider in hazard analysis.
The cooling of Portland cement clinker is a sensitive process requiring a certain degree of fast cooling. The fast cooling prevents reconversion of C 3 S to C 2 S + C. However, if the cooling is too fast, the clinker will end up with a significant amount of glassy phase, which will negatively impact the hydration necessary for concrete hardening.
Step 5 : Clinker Cooler. The clinker tumbles onto a grate system cooled by forced air. Once cooled the clinker is ready to be ground into the gray powder known as Portland cement. To save energy, heat recovered is recirculated back to the kiln and preheater tower.
The fine microstructure of cement clinker provides a number of clues relating to the state of the process which made it, including the temperature, the chemistry, the fuel type and quality, the thermal profile through the process and the efficiency of cooling.
