Abstract: A disc hog for reducing timbers to wood chips and shards of a predetermined maximum size comprises a housing defining a disc-shaped interior cavity and a heavy metal disc disposed in the cavity and mounted for rapid rotation about its central axis. A feeder opening is formed in the housing and a chute is positioned to facilitate the feeding of timbers through the opening for presentation to the front surface of the rotating disc. Both the front surface and the rear surface of the rotating disc is studded with hammer blocks that protrude outwardly from the surface. The hammer blocks on the front surface are sized and configured to impact, tear apart, and shred a timber fed to the disc into wood chips and shards. The hammer blocks on the rear surface of the disc are sized and configured to reduce wood shards and chips to shards of smaller size. Means are provided for drawing shards from the vicinity of the front surface of the disc and delivering them to the vicinity of the rear surface of the disc for simultaneous processing of shards on each side of the disc to reduce timbers to shards of a predetermined maximum size in a single operation.

Abstract: An improved wood pulverizer is provided with a rotating disc studded with a plurality of curved tapered hammers. One or more anvils is secured to the pulverizer with the anvil having teeth and slots located adjacent the surface of the disc. The hammers of the rotating disc pass through the slots of the anvils as the disc rotates to tear and shard wood into bits and pieces for subsequent use or processing. The anvils of the present invention are formed with two or more useable surfaces so that the anvils can be removed, rotated, and replaced to present fresh cutting surfaces to the disc. Further, the anvils are formed by a series of bolted together anvil segments to allow replacement of only single segments in the event of damage.
