How Do Rotary Kiln Dams Work?, 3D Illustration of a Rotary Kiln Dam for Increasing Retention Time

Dams are used to increase the retention time or bed depth in a rotary kiln. Material builds up behind the dam, forcing retention time and bed depth to increase. Material then spills over the dam and discharges from the rotary kiln. Since most rotary kilns …

Indirect Batch Kiln

Today’s photo shows an indirect batch rotary kiln in the FEECO Innovation Center. Indirect kilns heat solids to the point where a desired chemical reaction or phase change takes place. Unlike their direct-fired counterparts, indirect kilns are used when a material cannot come into contact …
