Effect of chemical composition of clinker on grinding
Grinding was carried out in a laboratory ball mill with 20kg capacity. Size distribution of the mill charge is given in Table 2. Grinding was stopped at predefined time intervals to determine the specific surface area of the ground clinker. Blaine fineness values were determined according to ASTM C204.

What is meant by fineness of cement, and why it is necessary?
Jan 29, 2019 · Bleeding can be reduced by increasing fineness. However, increased fineness can also lead to the requirement of more water for workability, resulting in a higher possibility of dry shrinkage. Fineness test is used to check the proper grinding of cement and measures the surface area of the cement particles per unit mass. FINENESS LIMIT:

How to Grind Coffee Learn About Coffee Grinding
You control the fineness of the grind by "pulsing" the power button until you''re satisfied. It can be difficult to judge how much coffee to grind, and how finely to grind it, however. Another downfall – if you are grinding finely, and therefore leaving the beans in the grinder longer, there can be significant heat created by the blades.
