Part 1 of this article [1] examined basic process principles and measuring methods. This second part focuses on the results for the kiln line. An increase in kiln output of up to a maximum of 30 % (from 54 to 70 t/h) was attained. A downward trend was apparent in energy consumption. A reduction in specific energy consumption from 3704 to 3633 kJ/kg clinker was measured, averaged across the entire test period. Even lower energy consumptions were recorded during the test phase of operation at an increased kiln speed, during which a notable stabilisation of kiln operation was also observable. In...
