Cement Kilns: Clinker Coolers

Coolers are essential parts of rotary kiln systems. Clinker leaves the kiln at 1200°C or more. Clinker at this temperature has a heat content of 1.22 MJ/kg and must be cooled in order to: avoid wasting this heat energy; obtain clinker at a temperature suitable for grinding - less than 100°C

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been th
