FEECO is a leading manufacturer of highly engineered, custom rotary kilns for processing solids. Our high-temperature kilns have earned a reputation for their durability, efficiency, and longevity. Based on rotary drum technology, a rotary kiln consists of a large rotating cylinder (the drum) fitted with tires resting on trunnion wheels that help to facilitate rotation via a drive assembly. The horizontal drum is positioned on a slight slope to allow gravity to assist in moving material through the unit. Material is processed according to predetermined temperature profiles and retention times in order to cause a physical change or chemical reaction. The high temperatures required in rotary kiln processing, combined with heavy loads, mean rotary kilns must be designed to withstand significant thermal stressors, requiring expertise in both engineering and fabrication. Rotary kilns are available in direct- and indirect-fired configurations, the choice between which depends on the material properties, as well as the intended reaction. DIRECT-FIRED ROTARY KILNS Direct-fired kilns utilize direct contact between the material and process gas to efficiently process the material. Combustion can occur in a combustion chamber to avoid direct flame radiation, or the flame can be directed down the length of the kiln. Material is heated via contact with the gas stream. Direct-fired kilns can be of the co-current (parallel) or counter-current configuration, referring to the direction the combustion gasses flow in relation to the material. FEATURES Size: Up to 15′ diameter x 100’+ long (Up to 4.6m dia. x 30.5m+ long)
