Industrial Separation Equipment. The phrase "separating the wheat from the chaff" is very old - proving size separation has a long history. Separation by size is a fundamental dry material processing step and equipment selection has to be properly coordinated with the rest of the process in mind, particularly size reduction equipment.

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 high-speed hammer mills with small diameter rotors [3]. High tip speeds result in material striking the outlet screen at steep angles,
