how to reduce LSF?

Norew,

  LSF is one of the most basic quality control parameters used in the cement industry.

  You can find out more about LSF and other basic cement chemistry at this link;-

LSF is normally controlled by increasing or decreasing the percentage of limestone in the raw mix. So, to reduce the LSF you would decrease the amount of limestone in the raw mix.
