Rotary Kilns - FEECO International Inc.
The kiln is set at a slight slope to assist in moving material through the drum. 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.
