clinker factor Page 1 of 2 International Cement Review

Nov 10, 2010Re clinker factor. The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and . This means that c.1.55 tonnes of raw mix are required and c.0.55 tonnes of CO2 are lost due to calcination of the CaCO3 in the raw material. The clinker factor is therefore 0.65 x the amount of raw mix. Reply.

Material mix control in cement plant automation IEEE

The raw materials for cement production are limestone, silica, iron, and bauxite. A single raw material is seldom found with the required proportions of raw materials; thus, a measured proportion of the raw materials is used, in order to give the desired chemical and mineralogical composition to the clinker.
