    Corn bran at three moisture contents (6%, 13%, and 24% d.b.) and feed rates (11.89, 23.86, and 35.86 g s-1) was ground using a hammer mill operated at two different tip speeds (19.0 and 47.0 m s-1). Geometric mean diameter (GMD) and energy consumption were observed within a split-plot experimental design.

  • What is a Hammer Mill? wiseGEEK

    A hammer mill is a machine used to shred or crush materials into smaller pieces. The basic design of machines of this type involve a rotating shaft to which free-swinging hammers are attached. This assembly is enclosed by a drum which holds the material to be pulverized. A hopper feeds the source material into the drum.
