Cement Kilns: Grate Coolers - Cement Plants and Kilns in ...

This means that an efficient kiln consuming 3.2 GJ per tonne of clinker will only take in 1216 kg of air per tonne of clinker - i.e. the air/clinker ratio is 1.216. Using this air alone in the cooler would result in a clinker temperature of 399°C, so the extra air needed to obtain a reasonable temperature is surplus to
