Cement Rotary Kiln Design
The length of each part of a rotary kiln is designed based on the inner diameter (D) of the kiln shell.. 1) The length of the kiln head overhanging section (l 1): l 1 = (1.2~1.5) D. As the first section of a rotary kiln, l 1 is better not to be designed too long, or the length of the effective parts of the kiln will have to be shortened.. 2) The length of the preheating …
