particle size distribution in cement mill

Improving particle size distribution in cement

In the past, cement producers gauged cement fineness (i.e., cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill.

MILLING ANALYSIS OF PARTICLES AUTUMN 2010

The changing particle size distribution of the milled good as a function of time is most easy to characterize qualitatively if the material has initially only one particle size. At the start of milling the first size class is continually diminished, (Curve A Fig. 3) first faster and then slower. An average particle size class is initially built up.

AP-42, Appendix B.2 Generalized Particle Size Distributions

The concept of the "generic" particle size distribution is based on categorizing measured particle size data from similar processes generating emissions from similar materials. These generic distributions have been developed from sampled size distributions from about 200 sources. Generic particle size distributions are approximations.
