1. When processing fine materials, an indirect kiln avoids the risk of entrainment. When processing in a direct kiln, fine materials can become entrained in the process gas and carried out to the baghouse. An indirect kiln avoids this issue because there is minimal gas moving through the drum. 2. Less exhaust air treatment is required.
