ABSTRACT:
A unique hammermill for fiberizing sheet comprised of natural or synthetic fibers, that has a reduced tendency to clog entrance slots of the fibrous sheets into the interior of the hammermill. According to the invention, the hammermill has a nose bar deflector, mounted upstream of a feed slot and preferably extending along the entire length of the slot, to deflect fibers from the slot entrance, thereby preventing clogging of the slot. In one embodiment, the deflector is substantially triangular in cross section, wherein one side is affixed laterally along an upstream edge of a fibrous sheet feed slot, so that one side of the deflector slopes away from an internal surface of the hammermill shell to deflect fibers, carried along the surface of the shell, away from the feed slot, thereby preventing clogging. In other embodiments, the shape of the deflecting surface differs, but is designed to deflect fiber and particulates from the openings of downstream slots.
