Anti slug device for hammermills

Claim 1

In a portable feed grinder including; a mobile frame, an open topped tub structure having a stationary bottom wall and circular peripheral wall mounted for rotation on the generally vertical axis of the tub structure, said bottom wall having an opening therethrough, said opening extending generally radially from adjacent the axis of the tub structure toward said peripheral wall, a grinder rotor disposed in said opening and journaled for rotation on a generally horizontal axis extending longitudinally of the opening, said rotor including a rotor shaft and a plurality of axially and circumferentially spaced relatively movable hammers operatively carried by said shaft for common rotation therewith, a grinder screen underlying and partially encompassing said rotor, and means for imparting rotation to said tub and grinding rotation to said rotor; the combination of mounting plate means disposed adjacent one side of said opening in the bottom wall, a plurality of rigid plate-like relatively stationary hammer elements projecting in generally vertical planes from said mounting plate means and disposed in spacedapart parallel relationship transversely of the axis of said rotor, each of said relatively stationary hammer elements extending generally toward the opposite side of said opening laterally from said mounting plate means and between paths of travel of different spaced ones of said relatively movable hammer, said relatively stationary hammer elements being disposed above the axis of rotation of said rotor and below the top of a circle defined by the radially outer ends of said relatively movable hammers during rotation of the rotor.
