Variation in Fineness of Portland Cement and its Effects ...

Fineness of cement, a property determined by the level of grinding of clinker along with gypsum in cement mill, has a significant effect on strength of cement. According to A.M. NEVILLE [1], PRICE [2], BUREAU OF RECLAMATION [3], KUHL [4], F. W. LOCHER et al. [5], and E. C. HIGGINSON [6], the rate of hydration depends on the fineness of cement

Preparation Of Cement Raw Material | Cement Mill, …

Grinding: grinding all materials into required fineness by cement mill. Cement ball mill and vertical cement mill are two common types. Homogenizing: homogeneous kiln feed is the precondition of clinker production, so homogenization of raw materials guard a pass of cement plant.


fineness & production - International Cement Review

In principle, one should say that there is no general mathematical rule relating fineness and tph, for cement just as for raw meal. The reason is simply because this relation would be determined at least by two elements: the characteristics of the mill and the characteristics of the separator, if a closed circuit is assumed.

Fineness - an overview | ScienceDirect Topics

The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.
