reduction ratio of hammer mill

Comminution features in an impact hammer mill -

Impact hammer mill produces self-similar distribution of product with a high reduction ratio. Median size of product is exponentially related to the quantity of fines generated. Reduction ratio and specific energy are linearly related. The quantity of fines generated in the mill is an indirect measure of the mill wear.
