fineness - an overview | sciencedirect topics

6.3.3.1 Cement Fineness. 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

cement grinding unit | cement grinding plant | epc project

Cement grinding unit, or called cement grinding plant, is an individual grinding plant in the finished cement production.The new-type cement grinding units adopt pre-grinding technology. The cement grinding units not only reduce the particles of feeding materials, but also help to produce cracks and flaws inside the particles, which largely increase production capacity of cement mill, reduce
