Abstract
A shredding machine has a housing provided with an upwardly presented inlet, and in addition a rotor which revolves within the housing over an arcuate grate which is also in the housing. The rotor includes hammers, the tips of which describe a hammer circle that passes close to the arcuate grate. The hammers generate considerable windage as the rotor revolves, and to prevent this windage from being directed upwardly out of the inlet and thereby interfering with the flow of lightweight feed materials into and through the inlet, a deflector is mounted in the housing over the hammer circle, generally along that portion of the hammer circle that leads up to the top of the circle. The deflector directs the windage generally laterally across the inlet instead of upwardly out of it, and indeed causes much of the air to be drawn around and to a large measure discharged through the grate. As a result even light weight feed materials fall easily into the hammers.
