2-2 Lime Kiln Principles And Operations

separates from the gases in the cyclone, and flows into the kiln as a dry powder. The lime dust that escapes the cyclone is usually captured in an electrostatic precipitator and also enters the kiln dry. With this system, chains are not needed to dry the lime mud; the entire kiln length is available for heating and calcining. LIME KILN FANS
