Clinker CoolersClinker CementClinker and Cement

Nov 29, 2018 · Strictly speaking the cooling of clinker does not only start in the cooling tubes but already in the kiln. In the case of a planetary cooler the kiln burner pipe is always inserted into the rotary kiln so that a cooling zone behind the flame of 1.5 to 2.5 kiln diameters is created. This zone is called the "kiln

Reactions in the cement kilnclinkering

Clinker reactions in the kiln. A number of phases are formed in the clinker feed before the burning zone proper is reached. These intermediate phases dissociate in the burning zone and are not therefore found in clinker but assist in forming the final clinker minerals. Fast cooling of clinker is advantageousit makes for more

Cement millWikipedia

Clinker rapidly burned at the minimum temperature for combination, then rapidly cooled, contains small, defective crystals that grind easily. These crystals are usually also optimal for reactivity. On the other hand, long burning at excess temperature, and slow cooling, lead to large, well-formed crystals that are hard to grind and un-reactive.

Sep 15, 2017 · A cooling curve is an exponential graph that represents the cooling progress in a clinker cooler with respect to distance and cooling air volume. The independent variable (X-axis) is cooling air (or distance) and the dependent variable (Y-axis) is temperature. Below is an example of a cooling curve for temperature vs distance from feed end.
