The first rule of operating a rotary kiln without any problem is distributing the forces equally to each piers. This can be done best, by full contact on ring and supporter roller surfaces and minimum ovality in kiln shell. As known rotary kilns work in 3 4 slope depended on design, model and brand.
Previous work on exergy analysis of cement has sometimes been focused on the sub systems such as the rotary kiln 9, and the raw mill 10. Most work has been on using only the operating data of the cement industry for the exergy analysis. This does not give room for parametric analyses that could give . suggestions for improvement of the process.
Wet and semi-wet process kilns. The escalation of the size of rotary kilns occurred in parallel with the emerging pre-eminence in Britain of the Wet Process of manufacture. In 1900 the standard length of kilns was 60 ft, and many were sceptical as to the value of longer kilns.
