Pigment Grind: How to Efficiently Adjust the Fineness

Nov 10, 2015  In the industry, the fineness of grind is generally achieved with a 2-step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.

Fineness - an overview ScienceDirect Topics

The fineness of cement is a major factor influencing its rate of hydration since the reactions involved occur at its interface with water. Ordinary Portland cement (Types I and II) has a surface area between 3000 and 3500 cm 2 /g, while the surface area for rapid hardening Portland cement (Type III) ranges from 4000 to 4500 cm 2 /g.
