The diameter of the clinker balls increases and the granulation of the raw meal in the kiln starts earlier. Therefore more and bigger clinker balls have to be moved inside the kiln when the BZT is increasing. At the same time, the material bed in the kiln is lifted up more, which moves the center of gravity away from the kiln axis.

A raw mill is an equipment used to grind raw materials into "raw mix" during the manufacture of cement. Raw mix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement. How Does a Raw Mill Work in a Cement Plant? A raw mill comprises several components that work together to produce the …
