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. Improved chip sizing grates are also provided with the grates having replaceable reversible gullet liners and grate rings formed by ring segments that together define a grate liner. Rotor rings are provided in some embodiments.
