For a labeled diagram of components, visit FEECO.com/rotary-kilns/ ROTARY KILNS Rotary Kiln internals DIRECT ROTARY KILNS Direct rotary kilns use direct contact between the material and combustion gases to treat material based on predetermined temperature profiles. Various internals can be employed to further increase heat transfer efficiency. Rotary kilns can be designed for co-current or counter-current air flow. FEECO rotary kilns offer a tailored solution to specialized high-temperature bulk solids processing. FEECO engineers all rotary kilns according to the specific process and material...

For a labeled diagram of components, visit FEECO.com/rotary-kilns/ When specific atmospheric conditions are required for processing, FEECO offers state-of-the-art indirect kilns for specialized thermal treatment. In an indirect kiln setup, the rotating drum is sealed off and externally heated inside a heat shroud to prevent contact between the material and heating medium. Material is heated through contact with the drum shell. Indirect kilns offer three major distinctions compared to direct rotary kilns: 1. When processing fine materials, an indirect kiln avoids the risk of entrainment. When...

OPTIONAL COMPONENTS & SUPPORT EQUIPMENT SEALS DRIVE ASSEMBLY OPTIONS A variety of drive assembly options exist for dryers and coolers, with the choice between them depending on the amount of horsepower, and the overall size of the drum. Direct drive assemblies are also available. LEAF SEAL Leaf seals employ overlapping spring steel plates mounted on the housing and riding on the wear ring to create an effective seal. Both single- and double-leaf seals are available, with a relative leakage of around 1.0% - 5.0% depending on the type chosen. BELLOWS SEAL GEAR & PINION DRIVE The gear and pinion...

INTERNALS Rotary kilns can be fitted with a variety of custom internals to improve agitation, efficiency, and performance. REFRACTORY Direct-fired rotary kilns are typically provided with refractory to protect the drum shell from the high temperatures within. Refractory can be provided in either castable or brick form, with multiple layers possible. BED DISTURBERS FEECO can configure custom bed disturbers to promote agitation of the material bed for more uniform heat distribution. This is especially common in indirect-fired kilns, since the material is heated through contact with the shell. This...
