blaine verses feed in cement mill

  • Particle size analysis reduces cement manufacturing costs

    Composition is controlled by manipulating both the feed to the kilns and the reaction conditions, principally temperature. Milling circuits reduce the resulting clinker to fine cement. The traditional measure for fineness is Blaine number, but increasingly cement producers are switching to laser diffraction particle size measurement.

  • Cement grinding Vertical roller mills versus ball mills

    • cement is ground much finer than raw meal • the feed to a cement mill is often completely dry and is significantly more difficult to grind than raw materials • requirements to the particle size distribution of the finished product are much more strict when grinding cement than when grinding raw materials
