  • Calculate the Reduction Ratio and the Number of Milling ...

    2021-3-28 · Generally, we need a very high reduction ratio to go from the run of mine to the liberation size. Therefore, it is necessary to divide the total R:1 into smaller ratios, thus it refers to multiple units of size reduction. The milling work is done in two circuits, crushing and grinding. The grinding reduction ratio is very higher than the crushing.

    Reduction ratio is often measured by dividing the F80 by the P80. The F80 is the particle size where 80% of the feed material is smaller than that size. The P80 represents a particle size where 80% of the product is smaller. Reduction ratios will vary with each application within each family of Hammermills and by the amount of applied energy.
