limestone addition in cement grinding Home » limestone addition in cement grinding Clinker (cement) Wikipedia In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fused together without melting to the point of liquefaction) limestone and aluminosilie materials
In practice, portland-limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 /g is necessary to compensate for the strength reduction resulting from the addition of 1% limestone. 3. The mill type and process system play an important role.
