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.Get Price
