Feeder-breakers have very high capacities of up to 2000 tons/h, and are mainly intended for oversize control rather than achieving a high degree of size reduction. They are designed both to reduce the size of large coal lumps to less than 6–14 inches, and also to feed materials out of bins and onto conveyors or chutes.
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.
