The new calciner is erected in an 80 meter high tower next to the already existing heat exchanger tower. In the pre-combustion chamber the raw meal is preheated to 880 degrees Celsius by the waste heat of the rotary kiln. The "Schwanenhals" of the calciner ensures that the calorific value of the applied material is fully utilized. 

The new part of the plant will be erected during operation and completed in spring 2017.
