Hammer mills have a wide application in biomass size reduction because of their simple design, ruggedness and versatil ity [16]. Fine or especially difficult to grind materials are often best comminuted using highspeed hammer mills with small diameter rotors [3]. High tip speeds result in material striking the outlet screen at steep angles,
