Grate Cooler in Cement Plant | Cement Clinker Cooler for Sale

The grate cooler is a type of clinker coolers, it plays an important role in the clinker manufacturing process. The grate cooler in a cement plant cools and transports the cement clinker from the rotary kiln, and provides heating air (secondary air) for the rotary kiln and preheater.The performance of the grate cooler will directly affect the production efficiency, energy consumption, and ...

Optimizing Cement Strength

High quenching speed has the following advantages: 1) prevents the clinker from pulverizing due to C 2 S transformation; 2) makes the clinker ball produce internal stress and improves its grindability; 3) reduces the crystallization of C 3 A in clinker and improves the …

Oct 31, 2020· The only difference is, in Dry-process kiln — additional air is used for clinker cooling but in VSK, required combustion air is only used for cooling. Therefore, very fast cooling of clinker or quenching process is being avoided in VSK process and it may unable to prevent phase transformation due to slow cooling of clinker.

Clinker built (also known as lapstrake) is a method of boat building where the edges of hull planks overlap each other. Where necessary in larger craft shorter planks can be joined end to end into a longer strake or hull plank. The technique developed in northern Europe and was successfully used by the Anglo-Saxons, Frisians, Scandinavians, and typical for the Hanseatic cog.

A DRY QUENCHING PROCESS FOR WHITE CEMENT CLINKER …

By quenching the clinker nmediately or very shortly after it passes from he clinkering zone of the kiln, there is a tendncy to "freeze" the equilibrium which has been 6 et up at the clinkering temperatures among the arious compounds in the clinker. It will be unlecessary to enter into a specific discussion of the ndividual compounds or their ...

Cement Clinker Quality Control During Clinker Production ...

A process for cooling white clinker is described comprising the following phases: a) a phase of size reduction of the clinker leaving the rotary kiln in the aggregate form and sending of the clinker thus grinded to the next phase of cooling, in a time of about 1 second; b) a phase of cooling at temperatures lower than 400-500°C of the clinker coming from phase a), by spraying of an amount of ...

Burning and nodulization process of clinker in the rotary ...

Cooling kiln protects equipment and facilitates quenching the clinker to ensure the important forms of minerals like C3S, C2S, C3A, C4AF stay in it, so that proper clinker quality is maintained. Improper design of cooling fans can lead to poor clinker quality, high power consumption and even damage of the conveying system. Raw Mill Exhaust Fans

WO2011051962A2 - A process for manufacturing white cement ...

But in white clinker production, where the iron content is low, this is not an issue. Subsequently, to prevent the re-oxidation of the iron, "quenching" is performed. This consists of rapidly lowering the clinker temperature from 1200°C to below 600°C in a few seconds, as it leaves the kiln.

EP2803651A1 - Process for cooling white clinker and ...

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Jul 01, 2002· About 240 kg of Portland cement clinkers from two different plants (A and B) were sampled at the outlet of the quenching cooler and sieved into 11 classes ranging from >30 to <0.15 mm φ.Table 1 shows the average chemical compositions of Clinkers A and B. Chemical analysis and thin section microscopy were made for each class of the clinker nodules. . With Clinker A, investigations were …

Clinker at this temperature has a heat content of 1.22 MJ/kg and must be cooled in order to: avoid wasting this heat energy; obtain clinker at a temperature suitable for grinding - less than 100°C; rapidly cool ("quench") - the clinker, thus preserving reactive metastable high-temperature minerals in the clinker and maximising its strength ...

Quick quench of the clinker mineral must be completed within the kiln or it will not be achieved. Slowly quenched clinker causes the C 3 S to revert back to C 2 S and free lime. Further slow cooling causes the C 2 S fin the beta state or high-temperature form to change to the gamma state of C 2 S (a low temperature form).
