The effect of addition agents in grinding Portland cement
In the dry grinding of most materials in a ball mill or similar apparatus a degree of fineness is eventually reached when a noticeable decrease in the efficiency of grinding occurs The degree of fineness where this phenomenon occurs as measured by the specific surface of the material being ground varies greatly with different materials The accompanying effect in all cases however is
