Degree of kiln filling means volumetric filling percentage of kiln charge inside the kiln (i.e. charge volume divided by kiln volume).To get the heat transferred into the ineterior of the charge it is an advantage to get a low degree of filling in the kiln.For this reason it is often an advantage to use a high kiln speed, despite the reduce ...
Cement kiln dust is considered one of the wastes which are produced in a local cement production plant Portland cement manufacturing in Assiut Cement Company-Egypt, these materials were utilized as waste blended sand with various ratios.
