Size Reduction an overview ScienceDirect Topics

Milling operations at hammer mills typically involve two sequential sizereduction steps to arrive at the final particle size specification. The first stage of the size reduction process takes the asreceived biomass and converts it through grinding or chipping into a product that can be further preprocessed.

characteristic governing size reduction is hardness because almost all mechanical size reduction techniques involve somehow creating new surface area, and this requires adding energy proportional to the bonds holding the feed particles together. A common way of expressing hardness is the Mohs scale, on which talcum is a 1 and diamond is a 10.
