Kiln Control and Operation
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.
