ABSTRACT
The new burning line has been constructed on the basis of the 1 450 t/d kiln by transforming it into a dry process kiln; the increase in capacity has been obtained by setting up a pre-heating tower with precalcination RSP ONODA with separated air; the pre-heating tower comprises five stages which provide for better utilization of heat of the exhaust gases. Temperature is approximately 320°C at the output from the tower. The cooler has been replaced by a FULLER cooler of 70 m2 with 2 grates.
