definition of cement clinker raw mill

Nov 10, 2010 Re: clinker factor. The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and 100%. 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.
