2004-12-10  This mills produced ordinary Portland cement with a Blaine surface area of about 3000 cm 2 /g. The mill discharge had a fineness of about 1800 cm 2 /g and the material which enters the second compartment had only a fineness of about 800 cm 2 /g. Whereas the material which enters the ball mill in a Combi-grinding plant is much finer (∼2000 cm 2 /g). Therefore, this results can’t be transferred directly to the one compartment ball
