A second application in cement for the bulk material analyzer is raw mix proportioning.  An analyzer placed just upstream of the raw mill can monitor the chemistry of the raw mix and automatically trigger an adjustment in the proportions of the reclaimed stockpile and the correctives.  By doing so, the plant is able to reduce the variability in the raw mix, and later on the kiln feed.  Consistent kiln feed chemistry in turn leads to lower fuel consumption per ton of clinker produced.
