  • improving particle size distribution in cement production

    Assessingcement fineness. In the past,cementproducers gaugedcement fineness(i.e.,cementparticle size) by evaluating the specific surface area (SSA) or Blainefinenessand the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assessfinenessand help monitor the efficiency of the mill
