MODERNIZATION OF KILN LINE NO 1 IN THE DE UNA CEMENT WORKS

The Deuna cement works, a wholly-owned subsidiary of Dyckerhoff AG, ha s been modernised to meet the demands of today's market. The modernisa tion plan which has been implemented was designed with the emphasis on efficiency, environmental compatibility and product quality assurance . Kiln line no. 1 is an. example for the concept adopted. The operatin g results show the successfulness of the plant's modernisation: the cl inker throughput rate was increased from 1800 to 2700 tpd and the spec ific heat consumption was reduced by approximately 120 kcal/kg clinker at a 3.5% gas bypass rate for chlorine. Primary energy savings of up to 20% are achieved by the burning of used tyres.
