Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed The kiln is set at a slight slope to assist in moving material through the drum
The resulting lime mud is fed into a rotary kiln where it is dried and heated countercurrently by combustion gases from an oil or gas burner at the other end of the kiln As the mud temperature reaches about 800oC 1470oF in the calcination zone of the kiln
The rotary kiln is the most flexible of any lime kilns able to produce soft medium or hard burned as well as deadburned lime or dolime Gas cleaning edit All the above kiln designs produce exhaust gas that carries an appreciable amount of dust
