types of raw mill charge ratio in cement

Rawmill Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the

clinker factor Page 1 of 2 International Cement Review

Nov 10, 2010· 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. Reply
