Fineness of cement It may be recalled that one of the last steps in the manufacture of cement is the grinding of clinker mixed with gypsum. Because hydration starts at the surface of the cement particles, it is the total surface area of cement that represents the material available for hydration. Thus, the rate of hydration depends on the fineness of the cement particles and, for a rapid ...

Optimizing Primary Grinding Capacity. The relation of fineness of grind to the degree of liberation of the valuable minerals from the gangue is certainly a factor to be considered in optimizing the primary grind. This largely determines the grind-recovery curve and the point of maximum recovery, which is normally at a very fine grind.
