Approach The zone modeling approach adopted here is shown sche matically in Figure 1 The kiln is divided axially into zones of equal widths Within each zone there are three flowing streams the flame or jet the gases surrounding the flame or jet and the solid burden Within a given zone each stream is

ence between the maximum and minimum pin positions in the course of a kiln rotation is a measure of the shell ovality If the ovality at any pier exceeds empirically determined limits corrective action is required Shell ovality measurement is the only accurate predictor of refractory life

The output of clinker is between 880920 ton day before rotary kiln speedincrease but 10001020 ton day after speed increasing Clinker strength has been greatly improved and grindability has also been improved so each cement mill production from 38 ton hour to 40 tonhour

Re degree of kiln filling Degree of kiln filling means volumetric filling percentage of kiln charge inside the kiln ie charge volume divided by kiln volumeTo get the heat transferred into the ineterior of the charge it is an advantage to get a low degree of filling in the this reason it is often an advantage to use a high kiln speed despite the reduce residence time of the
