Abstract (en)

An agricultural hammermill achieves fine grind at practical production rates. Hammer tip speeds of 7620m/min are provided at 1800 rpm by providing hammers (140) of sufficient length to provide a tip path diameter of approximately 1.37m. In order to avoid excessive centrifugal stresses on the hammer rotor and components, hammers are tapered to reduce tip mass. Because of the high tip speeds, fine grind of feed grains is obtained usually with only a single impact of the hammers. Thus, since it is not necessary to retain the grain in the grinding chamber (150) for multiple hammer impacts, a large apertured screen can be used. <IMAGE>
