    g is the gravitational acceleration in ms 2, and. r P is the pitch diameter in m.. The optimum of Fr p is between 1.6 and 2.0. The milling capacity for Fr p outside this range is lower despite the constant energy consumption of the pulverizer.. Tests carried out for some industrial mills have proven that the change of grinding unit rotational speed strongly influences mill capacity.

    Oct 05, 2016 Due to the more energy-efficient grinding process, Cemex ground cement will usually have a steeper particle-size distribution curve than corresponding ball mill cements. Consequently, when ground to the same specific surface Blaine, Cemex cement will have lower residues on a 32 or 45 m sieve and tend to have a faster strength development.
