  • Kiln for Limestone Calcination

     · I have worked in steel and in lime. Typically, the steel mill will want lower sulfur lime. Reheat kilns and shaft kilns tend to capture the sulfur in the stone which results in higher sulfur lime. Traditional "long kilns" make lower sulfur lime and have been preferred for steel shops. Some mills pay a premium for the lime from long kilns.
