### Rotary Kilns For Cement Plants Flsmidth

modern cement plant. The 2-base rotary kiln is a statically determined beam system, where the support load is always known. It is a shorter and wider kiln, with a reduced slope to maintain the material retention time, similar to a 3-base kiln. The larger diameter reduces the gas velocity and the dust recircula-tion, and secures a lower burning zone

### Rotary Kiln Ispatguru
