Summary of production process. The material formed in the kiln is described as 'clinker' and is typically composed of rounded nodules between 1mm and 25mm across. After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder.

Estimating emissions generally involves two emission factors: an emission factor for clinker production and an emission factor for Cement Kiln Dust (CKD) production. The clinker emission factor is the product of the fraction of lime in the clinker multiplied by the ratio of the mass of CO2 released per unit of lime.

May 09, 2012· This process accounts for ~50 percent of all emissions from cement production. Indirect emissions are produced by burning fossil fuels to heat the kiln. Kilns are usually heated by coal, natural gas, or oil, and the combustion of these fuels produces additional CO 2 emissions, just as they would in producing electricity. This represents around 40 percent of cement emissions.
