Kiln shell cooling Page 1 of 1 International Cement Review

Mar 08, 2010· Re: Kiln shell cooling. High velocity forced-air shell cooling as part of a properly designed system, has a vital shell protection and shell life preservation function. This is not only in the burning zone, but can be even more important for the transition zone areas where coating may be either non-existent or transient.

Cement Cooling System Efficient, Industrial Cement

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 110ºC 120ºC, cooling to below 80ºC is necessary to avoid this reaction.

KILNCOOLER KIMA Process Control

With the application of KILNCOOLER, a hot spot can be cooled down rap­idly but care­fully, a­void­ing any shrink­age of the kiln shell—cool­ing rate is up to 2 Kelvin per minute. After cool-down the shell tem­per­a­ture is kept at its nom­i­nal value, thus e­lim­i­nat­ing me­chan­i­cal ten­sions.

Kiln cooling using water based KilnCooler KIMA Germany

Sep 06, 2017· Control your kiln shell temperature with a water based kiln cooling system. Reliable and effective cooler for kiln shell. Due to the increasing usage of secondary fuels, which are relatively in-homogeneous, there are more fluctuations in the burning process. This leads to increased burden for the refractory and the kiln shell hot-spots may occur.
