    The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the ' specific surface area ', which is the total particle surface area of a unit mass of cement.Cement Kilns: Size Reduction and Grinding,The mill came into use in the 1890s, initially for re-grinding rejects, both in dry rawmix and cement grinding. Later, they came to be used for the entire grinding process. Martin Earles first installed them for autonomous cement grinding in 1899, and in 1904, they were used exclusively at Norman for rawmilling, coal and cement grinding

  • Ball Mill & Roller Press Systems for Cement Grinding

    There are three main grinding processes in the cement production: raw meal grinding, cement grinding, and raw coal grinding. The power consumption of the cement grinding accounts for about 40% of the total power consumption of the cement production process. The finished product cement from this system also has wide particle sizeMeasuring the Size Distribution of Cement in Real Time,fineness of the grind, the distribution of particle size, and the efficiency of separation of the finely ground particles. The finer the grind, the more reactive is the finished cement. Rapid-setting cements have smaller particle size than the 70% 17% 8% 5% Coal
