ABSTRACT:
A plurality of chipper inserts that may be installed on a hammermill rotor in place of the hammer inserts to selectively convert the rotor to a chipper. The chipper inserts include drum surfaces that cooperatively define a chipper drum. The chipper inserts may include cutter inserts that have a cutter disposed in a cutter pocket. The chipper drum may be a generally continuous cylindrical interrupted essentially only by the cutter pockets. The cutters and cutter pockets may be positioned in essentially any desired pattern around the drum. The chipper inserts may include a left cutter insert, a center cutter insert, a right cutter insert and three different size spacer inserts. The different types of cutter inserts and spacer inserts may be installed about the rotor with at least one left cutter insert mounted on the left end of the chipper drum and at least one right cutter insert mounted on the right end of the chipper drum. The chipper inserts may be configured in quadrant sections, such that it takes four inserts to extend around the rotor.
